+Replaced the 4.0 branch by a copy of the trunk (in order to keep the
+history of the latest changes of the trunk); this replacement is due
+to a limitation of Subversion where a merge is regarded as a single
+commit, and is OK here since the 4.0 branch is new.

+[tests] Solve issues with the incorrect use of mpfr_sgn, and make sure
+that this cannot happen again without being detected: on zero, +1 or -1
+was sometimes expected to check the sign of zero, but mpfr_sgn actually
+returned 0, so that the check always succeeded whatever the sign of the
+null result.
+ * mpfr-test.h: define a new mpfr_sgn macro that fails when used on NaN
+ or zero (whose sign is not +1 or -1), except when MPFR_TESTS_TSGN is
+ defined.
+ * tacos.c, tasin.c, tasinh.c, tatanh.c, tcbrt.c, tdim.c, terf.c,
+ texp.c, texp10.c, texp2.c, texpm1.c, tset.c, tset_str.c: replaced
+ the incorrect use of mpfr_sgn; some other related improvements.
+ Note: in tset.c, a "mpfr_sgn (x) < 0" test had to be replaced by
+ "MPFR_IS_POS (x)" since we really want to test whether the sign
+ is positive (not negative).
+ * tdiv.c, tmul.c, tui_div.c: simplified some tests, in particular to
+ avoid a failure with the new mpfr_sgn macro for the tests; here,
+ the use of mpfr_sgn was correct, but one could do simpler.
+ * tgmpop.c: replaced "mpfr_sgn (z)" by "(mpfr_sgn) (z)" to avoid the
+ new mpfr_sgn macro (here, we really want the mathematical sign).
+ * tsgn.c: define MPFR_TESTS_TSGN as the goal of this program is to
+ test mpfr_sgn itself (both the function and the macro in mpfr.h).

-In details:
- * The computation of the number of characters to be written could
- be incorrect by 1 when the thousands separator was not empty.
- However, in the 3.1 branch (without additional patches), this
- value is currently only used for overflow checking, so that this
- bug could have only very little effect (contrary to the trunk).
- * When the int and long types have the same size, the code assumed
- "wrapping behavior in two's complement". But this is actually
- undefined behavior in ISO C; in practice, a smart compiler may
- have ignored "total < 0" tests, because total is computed with
- sums of non-negative integers.

+[tests/tests.c] Change for MPFR_TESTS_DIVBYZERO: in case of FE_DIVBYZERO
+or FE_INVALID, fail unconditionally, not just when MPFR_ERRDIVZERO is
+defined, otherwise one cannot see the output about the floating-point
+exceptions with "make check" (the test of MPFR_ERRDIVZERO here should
+have been removed after switching to Automake 1.13, which discards the
+output when the test program succeeds).
+Note: defining MPFR_TESTS_DIVBYZERO without MPFR_ERRDIVZERO is just for
+debugging.

+[tests] Define global variable tests_memory_disabled, which needs to
+be set when the memory.c allocators (to track memory leaks) must not
+be used; i.e., setting it disables the calls to tests_memory_start()

[tests] C++ compatibility: avoid errors with "g++ -std=c++11" or later.
Note that as of GCC 6, "the default mode for C++ is now -std=gnu++14
instead of -std=gnu++98" <https://gcc.gnu.org/gcc-6/changes.html>.
So, this fixes the failures in the build of the MPFR tests with g++
from GCC 6 without particular options.

+Merged the "ubf" branch into the trunk:
+ * limited implementation of "unbounded floats" (numbers with a mpz_t
+ exponent), which could be completed in the future, in particular to
+ handle intermediate overflows/underflows in polynomial evaluation;
+ * rewrote mpfr_fmma and mpfr_fmms to use them, and added tests;
+ * restored the MPFR 3.1- exponent range for compatibility;
+ * restored some tests that were based on this exponent range.
+The choice for the UBF implementation was to use a compatible structure:
+the same as the mpfr_t one, with an additional field at the end, used
+only when the exponent field _mpfr_exp has some special value. Thus some
+functions such as addition and subtraction just needed minor changes to
+support UBF, and no code was duplicated. This means that on MPFR numbers
+(the usual case), one has a few more tests than before, but with known
+branch probabilities. In practice, this should not be visible, at least
+in most applications. This was more or less confirmed by timings (even
+with many additions/subtractions in low precision, this was difficult
+to say, as timings were influenced by various parameters that we cannot
+control).

-[src/sum.c] Fixed bugs in mpfr_sum, which could return wrong results
- when not all the numbers have the same precision. A side effect is
- that this can make mpfr_sum much slower and/or take much more memory
- in some of such cases with the same program; this is normal and
- cannot easily be avoided with the current algorithm.
- Note: The full rewrite currently in the trunk has not been merged
- because this would not be a simple patch (and it is still incomplete
- when a number is reused as the output).
-[src/mpfr-impl.h] Updated the prototype of mpfr_sum_sort.
- Note: Since this function is used only internally and by the tests,
- this does not break the ABI. However the old and new tsum tests are
- source & binary incompatible.

-crash or take much memory, and the function could return incorrect

+[tests/mpf_compat.h] Fix: File "inp_str.dat" could not be opened with
+builds outside the source directory (objdir different from srcdir).
+This did not generate an error, but prevented a test from being done.
+Now that mpfr-test.h is included via the mpf_compat.c or mpfr_compat.c

+[tests/mpf_compat.h] For mpf_set_str and mpf_init_set_str, avoid strings
+with ".", since for GMP the decimal separator is locale dependent (the
+tests can be run in non-C locales on purpose in order to detect issues
+in various locales), so that for the mpf_compat test, the conversion
+fails and the mpf value x is set to 0 (which can yield other problems,
+such as with mpf_div (y, x, x), which raises an exception).
+Note: this problem appeared in r9157, where tests_start_mpfr() was added
+to mpf_compat.h (the locale setting is done in this function).

+Merged the set_exp branch into the trunk. Changes:
+ * src/mpfr-impl.h: updated the MPFR_SET_EXP(x, exp) definition for
+ the MPFR_EXP_CHECK case. There are 2 consequences:
+ 1. The exp expression is evaluated several times (this should be
+ OK with the MPFR code and optimizations).
+ 2. The real value of exp is tested for the assertion, instead of
+ the value converted to mpfr_exp_t. Thus new bugs could be found
+ (e.g. when an unsigned type is used instead of signed).
+ * src/set_exp.c: set the exponent only if x is a non-zero ordinary
+ number, i.e. already has a valid significand and a valid exponent
+ (thus it is no longer a low-level function, and it can no longer
+ generate an invalid value from a valid one).
+ * doc/mpfr.texi: updated mpfr_set_exp description and added an item
+ in the "API Compatibility / Changed Functions" section.
+ * Clean-up.

+
+When static assertions are not supported by the C implementation
+natively (new C11 feature), their MPFR implementation got broken by
+changeset r8625, as the __MPFR_GNUC macro in mpfr-sassert.h was not
+defined in the configure test (since mpfr-impl.h wasn't included)
+and generated an error, disabling the static assertions support.
+This is fixed by the following changes, avoiding code duplication
+and thus risk of inconsistencies in future modification:
+ * copied some of the version detection macros from mpfr-impl.h to
+ a standalone file mpfr-cvers.h, and updated the macros;
+ * in mpfr-impl.h, replaced these macros by a #include "mpfr-cvers.h"
+ and updated a comment;
+ * in mpfr-sassert.h, added a #include "mpfr-cvers.h".

- outputting 0 with the '#' flag, a positive precision, and the 'g'/'G'
- conversion specifier: there was one additional trailing 0.
-[tests/tsprintf.c] Corrected the corresponding test.
-(merged changesets r8705-8706 from the trunk)
+[doc/README.dev] This may seem obvious, but this is not the first time
+this happens: + "When adding the expected result, do NOT use the one
+obtained from the MPFR function! Otherwise, if this function is buggy,
+the test will be wrong and the function will remain buggy."

+Daniel Richard G. for the patch; kept the autoconf requirement
+to 2.60 instead of changing it to 2.68 as done with autoupdate,
+since 2.60 seems to be sufficient according to the changes and
+2.68 is too recent, e.g. Debian/stable still has 2.67).
+--- Note ---
+This update has another effect: The "Configs for Windows DLLs."
+code (from "case $host in" to "esac") is now executed at the right
+time, after options like --disable-static are taken into account.
+Juste before this change, the test
+ if test "$enable_shared" = yes; then
+was always false. This could be seen on hydra:
+With r8360:
+[...]
+configure flags: --disable-static --disable-dependency-tracking
+ --prefix=/nix/store/95zhbb0v23syxsazx33hg3acbvixyq5a-mpfr-0-3.2.0-dev

+[src/mpfr-intmax.h] Define MPFR_USE_INTMAX_T if <inttypes.h> and/or
+<stdint.h> is available. This is needed on systems for which the
+current (non-standard) macro tests in mpfr.h is not sufficient.
+This will force the support of intmax_t/uintmax_t in this case and
+also avoids a failure in the tests on such systems.
+Tested by replacing the macro tests in mpfr.h by just
+ #if defined (MPFR_USE_INTMAX_T)
+to simulate such a system.

+[src] New mpfr_flags_t type, defined as an unsigned int. For the
+ __gmpfr_flags variable and internal flags-related variables,
+ replaced unsigned int by mpfr_flags_t (note that this doesn't
+ change the ABI, since unsigned int was already used).
+[tests] Cast __gmpfr_flags to unsigned int when printed with %u.

-Avoid potential integer overflows and improve consistency. This should

-Note: this problem appeared in MPFR 3.0.0 when the precision type (now
-mpfr_prec_t) was changed to a signed integer.
-Added a large precision test in tests/tinits.c (enabled by setting
-MPFR_CHECK_LARGEMEM=1) to trigger the bug mentioned above on 32-bit
-machines (or when MPFR is built with -m32).

Corrected a typo in MPFR_LOG_FUNC of add_d.c, add_ui.c and mul_d.c
(mpfr_get_prec → mpfr_log_prec), fixing bug 13933.
The consequence was random freezes (on the same binary) with dynamic
linking (and just more memory with static linking to the MPFR library)
when logging was used.

- * [src/mpfr-impl.h] Define new macros MPFR_EXT_EMIN and MPFR_EXT_EMAX.
- * [src/agm.c] Replaced __gmpfr_emin and __gmpfr_emax by MPFR_EXT_EMIN
- and MPFR_EXT_EMAX respectively (this should be a bit faster with TLS
- and also is a workaround to a bug occurring with TLS and GCC 4.3.2
- on a Linux/Sparc machine, gcc54.fsffrance.org).
- * [tests/tgmpop.c] Check for erange flag in mpfr_cmp_[f,q,z].
- * [src/gmp_op.c] Handle the special cases in mpfr_cmp_q and mpfr_cmp_f
- (fixing the problem with the erange flag in particular).
- * [src/buildopt.c,src/mpfr.h,tests/tbuildopt.c,doc/mpfr.texi,NEWS]
- Added mpfr_buildopt_gmpinternals_p function.
- * [examples/version.c] Output mpfr_buildopt_gmpinternals_p() and
- mpfr_buildopt_tune_case() values with MPFR 3.1 or later.
- * [doc/README.dev] Updated "To make a release". Document how to
- specify the minimum exponent or the maximum exponent.
- * [TODO] Added an item about the minimum and maximum exponents.

##############################################################################
-Changes from version 3.1.5 to version 3.1.6:
+Changes from versions 3.1.* to version 4.0.0:
+- The "dinde aux marrons" release.
+- MPFR now depends on GMP 5.0+ instead of 4.1+.
+- API change:
+ Applications that call GMP's mp_set_memory_functions function to change
+ the allocators must first call the new function mpfr_mp_memory_cleanup
+ in all threads where MPFR is potentially used; this new function is
+ currently equivalent to mpfr_free_cache.
+ The reason is that the way memory allocation is done by MPFR has changed
+ (again), so that the current GMP allocators are used (since for some
+ applications, the old allocators may become invalid).
+ Note: Freeing the caches like this might have a performance impact on some
+ particular applications; if this is an issue, this could be handled for a
+ future MPFR version.
+- Mini-gmp support via the --enable-mini-gmp configure option (experimental).
+- The minimum precision MPFR_PREC_MIN is now 1, with rounding defined as
+ in the errata of IEEE 754-2008 and in the following IEEE 754 revision
+ (ties rounded away from zero).
+- Shared caches for multithreaded applications.
+ New function mpfr_free_cache2.
+- Partial support of MPFR_RNDF (faithful rounding).
+- New functions: mpfr_fpif_export and mpfr_fpif_import to export and import
+ numbers in a floating-point interchange format, independent both on the
+ number of bits per word and on the endianness.
+- New function mpfr_fmodquo to return the low bits of the quotient
+ corresponding to mpfr_fmod.
+- New functions mpfr_flags_clear, mpfr_flags_set, mpfr_flags_test,
+ mpfr_flags_save and mpfr_flags_restore to operate on groups of flags.
+- New functions mpfr_set_float128 and mpfr_get_float128 to convert from/to
+ the __float128 type (requires --enable-float128 and compiler support).
+- New functions mpfr_buildopt_float128_p and mpfr_buildopt_sharedcache_p.
+- New functions mpfr_rint_roundeven and mpfr_roundeven, completing the
+ other similar round-to-integer functions for rounding to nearest with
+ the even-rounding rule.
+- New macro mpfr_round_nearest_away to add partial emulation of the
+ rounding to nearest-away (as defined in IEEE 754-2008).
+- New functions mpfr_nrandom and mpfr_erandom to generate random numbers
+ following normal and exponential distributions respectively.
+- New functions mpfr_fmma and mpfr_fmms to compute a*b+c*d and a*b-c*d.
+- New function mpfr_rootn_ui, similar to mpfr_root, but agreeing with the
+ rootn function of the IEEE 754-2008 standard.
+- New functions mpfr_log_ui to compute the logarithm of an integer,
+ mpfr_gamma_inc for the incomplete Gamma function.
+- New function mpfr_beta for the Beta function (incomplete, experimental).
+- New function mpfr_get_q to convert a floating-point number into rational.
+- The mpfr_dump function is now described in the manual; its output format
+ has slightly changed.
+- The mpfr_eint function now returns the value of the E1/eint1 function
+ for negative argument.
+- The behavior of the mpfr_set_exp function changed, as it could easily
+ yield undefined behavior in some cases (this modifies both the API and
+ the ABI).
+- In function mpfr_urandom, the next random state no longer depends on the
+ current exponent range and the rounding mode. The exceptions due to the
+ rounding of the random number are now correctly generated, following the
+ uniform distribution.
+- Functions mpfr_grandom and mpfr_root are deprecated and will be removed
+ in a future release.
+- Complete rewrite of function mpfr_sum, which now works in all cases (the
+ old one could take all the memory and/or crash with inputs of different
+ magnitudes in case of huge cancellation or table maker's dilemma). The
+ sign of an exact zero result is now specified, and the return value is
+ now the usual ternary value. Note that the position of "const" in the
+ mpfr_sum prototype has been fixed (the manual was correct); user code
+ should not be affected.
+- Old, deprecated macros mpfr_add_one_ulp and mpfr_sub_one_ulp removed.
+ The mpfr_next* functions should be used instead.
+- Internally, improved caching: a minimum of 10% increase of the precision
+ is guaranteed to avoid too many recomputations.
+- Added internal small-precision mpz_t pool, which aims to avoid the
+ overhead of memory allocation, in particular.
+ New function mpfr_free_pool.
+- Added configure option --enable-assert=none to avoid checking any assertion.
+- The --enable-decimal-float configure option no longer requires
+ --with-gmp-build, and support for decimal floats is now automatically
+ detected by default (similarly for support for __float128).
+- Updated tuning parameters.
+- Better support for Automake 1.13+ (now used to generate the tarball).
+- Dropped K&R C compatibility.
- Improved MPFR manual.
-- Bug fixes (see <http://www.mpfr.org/mpfr-3.1.5/#fixed> and ChangeLog file).
+- New MPFRbench program (see the tools/bench directory).
+- Major speedup in mpfr_add, mpfr_sub, mpfr_mul, mpfr_div and mpfr_sqrt when
+ all operands have the same precision and this precision is less than twice
+ the number of bits per word, e.g., less than 128 on a 64-bit computer.
+- Speedup by a factor of almost 2 in the double <--> mpfr conversions
+ (mpfr_set_d and mpfr_get_d).
+- Speedup in mpfr_log1p and mpfr_atanh for small arguments.
+- Speedup in the mpfr_const_euler function (contributed by Fredrik Johansson),
+ in the computation of Bernoulli numbers (used in mpfr_gamma, mpfr_li2,
+ mpfr_digamma, mpfr_lngamma and mpfr_lgamma), in mpfr_div, in mpfr_fma
+ and mpfr_fms.
+- Test coverage: 96.3% lines of code.
+- Bug fixes. In particular: a speed improvement when the --enable-assert
+ or --enable-assert=full configure option is used with GCC; mpfr_get_str
+ now sets the NaN flag on NaN input and the inexact flag when the conversion
+ is inexact. For a full list, see http://www.mpfr.org/mpfr-3.1.6/#fixed
+ and the same section for any previous 3.1.x version (follow the links
+ in the "Changes..." sections).
+- Microsoft Windows: Added support for thread-safe DLL (shared library).
+ Tested with MinGW, ICC and MSVC.
+- Limited pkg-config support.
- Autotools: Under Linux, make sure that the old dtags (when supported)
are used if LD_LIBRARY_PATH is defined; otherwise "make check" would
check an installed, compatible MPFR library found in LD_LIBRARY_PATH
instead of the one that has been built with "make".

+ https://gmplib.org/list-archives/gmp-devel/2015-September/004147.html
+ Summary: It will not be integrated in GMP because 1) This yields

+ arctan(x) took 0.035401 ms (32767 eval in 1160 ms)
+ mpfr_acos doesn't use mpz, but calls mpfr_atan, so that the issue comes
+ from mpfr_atan, which uses mpz a lot. The problem mainly comes from the
+ reallocations in GMP because mpz_init is used instead of mpz_init2 with
+ the estimated maximum size. Other places in the code that uses mpz_init
+ may be concerned.
+ Issues with mpz_t caching:
+ * The pool can take much memory, which may no longer be useful.
+ For instance:
+ mpfr_init2 (x, 10000000);
+ mpfr_log_ui (x, 17, MPFR_RNDN);
+ /* ... */
+ mpfr_clear (x);
+ /* followed by code using only small precision */
+ while contrary to real caches, they contain no data. This is not
+ valuable memory: freeing/allocating a large block of memory is
+ much faster than the actual computations, so that mpz_t caching
+ has no impact on the performance in such cases. A pool with large
+ blocks also potentially destroys the data locality.
+ * It assumes that the real GMP functions are __gmpz_init and
+ __gmpz_clear, which are not part of the official GMP API, thus
+ is based on GMP internals, which may change in the future or
+ may be different in forks / compatible libraries / etc. This
+ can be solved if MPFR code calls mpfr_mpz_init / mpfr_mpz_clear
+ directly, avoiding the #define's.
+ Questions that need to be answered:
+ * What about the comparisons with other memory allocators?
+ * Shouldn't the pool be part of the memory allocator?
+ For the default memory allocator (malloc): RFE?
+ If it is decided to keep some form of mpz_t caching, a possible solution
+ for both issues: define mpfr_mpz_init2 and mpfr_mpz_clear2, which both
+ take 2 arguments like mpz_init2, where mpfr_mpz_init2 behaves in a way
+ similar to mpz_init2, and mpfr_mpz_clear2 behaves in a way similar to
+ mpz_clear but where the size argument is a hint for the pool; if it is
+ too large, then the mpz_t should not be pushed back to the pool. The
+ size argument of mpfr_mpz_init2 could also be a hint to decide which
+ element to pull from the pool.
+
+- in tsum, add testcases for mpfr_sum triggering the bug fixed in r9722,
+ that is, with a large error during the computation of the secondary term
+ (when the TMD occurs).
+
+- add internal or public variants of some basic functions (+, -, *) with
+ mpz_t as the exponent for correctly rounded polynomials (like fmma),
+ in order to avoid internal overflow and underflow in extreme cases?
+ Alternatively, for fmma, modify add*.c and sub*.c code to define
+ mpfr_add_raw, which takes arrays of limbs and their precision, and the
+ positive exponent delta (as mpfr_uexp_t to be always representable).
+ The exponent delta should be sufficient for now since it can be bounded
+ by MPFR_PREC_MAX+1 if need be.
+
+- use the keyword "static" in array indices of parameter declarations with
+ C99 compilers (6.7.5.3p7) when the pointer is expected not to be null?
+ For instance, if mpfr.h is changed to have:
+ __MPFR_DECLSPEC void mpfr_dump (const __mpfr_struct [static 1]);
+ and one calls
+ mpfr_dump (NULL);
+ one gets a warning with Clang. This is just an example; this needs to be

+
+- change most mpfr_urandomb occurrences to mpfr_urandom in the tests?
+ (The one done in r10573 allowed us to find a bug even without
+ assertion checking.)
+
+- tzeta has been much slower since r9848 (which increases the precision
+ of the input for the low output precisions), at least with the x86
+ 32-bit ABI. This seems to come from the fact that the working precision
+ in the mpfr_zeta implementation depends on the precision of the input.
+ Once mpfr_zeta has improved, change the last argument of test_generic
+ in tzeta.c back to 5 (as it was before r10667).
+
+- check the small-precision tables in the tests?
+ This may require to export some pointer to the tables, but this could
+ be done only if some debug macro is defined.
+
+- optionally use malloc() for the caches? See mpfr_mp_memory_cleanup.
+ Note: This can be implemented by adding a TLS flag saying whether we
+ are under cache generation or not, and by making the MPFR allocation
+ functions consider this flag. Moreover, this can only work for mpfr_t
+ caching (floating-point constants), not for mpz_t caching (Bernoulli
+ constants) because we do not have the control of memory allocation for
+ mpz_init.

+ * Sampling from the exponential distribution with unit mean using the method
+ * given in John von Neumann, Various techniques used in connection with random
+ * digits, in A. S. Householder, G. E. Forsythe, and H. H. Germond, editors,
+ * "Monte Carlo Method", number 12 in Applied Mathematics Series, pp. 36-38
+ * (NBS, Washington, DC, 1951), Proceedings of a symposium held June 29-July 1,
+ * 1949, in Los Angeles.
+ *
+ * A modification to this algorithm is given in:
+ * Charles F. F. Karney,
+ * "Sampling exactly from the normal distribution",
+ * ACM Trans. Math. Software 42(1), 3:1-14 (Jan. 2016).
+ * https://dx.doi.org/10.1145/2710016
+ * http://arxiv.org/abs/1303.6257
+ * Although this improves the bit efficiency, in practice, it results in
+ * a slightly slower algorithm for MPFR. So here the original von Neumann
+ * algorithm is used.
+ *
+ * There are a few "weasel words" regarding the accuracy of this
+ * implementation. The algorithm produces exactly rounded exponential deviates
+ * provided that gmp's random number engine delivers truly random bits. If it
+ * did, the algorithm would be perfect; however, this implementation would have
+ * problems, e.g., in that the integer part of the exponential deviate is
+ * represented by an unsigned long, whereas in reality the integer part in
+ * unbounded. In this implementation, asserts catch overflow in the integer
+ * part and similar (very, very) unlikely events. In reality, of course, gmp's
+ * random number engine has a finite internal state (19937 bits in the case of
+ * the MT19937 method). This means that these unlikely events in fact won't
+ * occur. If the asserts are triggered, then this is an indication that the
+ * random number engine is defective. (Even if a hardware random number
+ * generator were used, the most likely explanation for the triggering of the
+ * asserts would be that the hardware generator was broken.)

+/* The format is described as follows. Any multi-byte number is encoded
+ in little endian.
+
+ 1. We first store the precision p (this format is able to represent
+ any precision from 1 to 2^64 + 248).
+ Let B be the first byte (0 <= B <= 255).
+ * If B >= 8, the precision p is B-7.
+ Here, the condition is equivalent to 1 <= p <= 248.
+ * If B <= 7, the next B+1 bytes contain p-249.
+ Here, the condition is equivalent to 249 <= p <= 2^64 + 248.
+ We will use the following macros:
+ * MPFR_MAX_PRECSIZE = 7
+ * MPFR_MAX_EMBEDDED_PRECISION = 255 - 7 = 248
+
+ 2. Then we store the sign bit and exponent related information
+ (possibly a special value). We first have byte A = [seeeeeee],
+ where s is the sign bit and E = [eeeeeee] such that:
+ * If 0 <= E <= 94, then the exponent e is E-47 (-47 <= e <= 47).
+ * If 95 <= E <= 110, the exponent is stored in the next E-94 bytes
+ (1 to 16 bytes) in sign + absolute value representation.
+ * If 111 <= E <= 118, the exponent size S is stored in the next
+ E-110 bytes (1 to 8), then the exponent itself is stored in the
+ next S bytes. [Not implemented yet]
+ * If 119 <= E <= 127, we have a special value:
+ E = 119 (MPFR_KIND_ZERO) for a signed zero;
+ E = 120 (MPFR_KIND_INF) for a signed infinity;
+ E = 121 (MPFR_KIND_NAN) for NaN.
+
+ 3. Then we store the significand (for regular values).
+
+ The sign bit is preserved by the import/export functions, even for NaN.
+
+ Note: When a size is stored, it must be minimal, i.e. a number cannot
+ start with a null byte. Otherwise the import may fail.

+ * Sampling from the normal distribution with zero mean and unit variance.
+ * This uses Algorithm N given in:
+ * Charles F. F. Karney,
+ * "Sampling exactly from the normal distribution",
+ * ACM Trans. Math. Software 42(1), 3:1-14 (Jan. 2016).
+ * https://dx.doi.org/10.1145/2710016
+ * http://arxiv.org/abs/1303.6257
+ *
+ * The implementation here closely follows the C++ one given in the paper
+ * above. However, here, C is simplified by using gmp_urandomm_ui; the initial
+ * rejection step in H just tests the leading bit of p; and the assignment of
+ * the sign to the deviate using gmp_urandomb_ui. Finally, the C++
+ * implementation benefits from caching temporary random deviates across calls.
+ * This isn't possible in C without additional machinery which would complicate
+ * the interface.
+ *
+ * There are a few "weasel words" regarding the accuracy of this
+ * implementation. The algorithm produces exactly rounded normal deviates
+ * provided that gmp's random number engine delivers truly random bits. If it
+ * did, the algorithm would be perfect; however, this implementation would have
+ * problems, e.g., in that the integer part of the normal deviate is
+ * represented by an unsigned long, whereas in reality the integer part in
+ * unbounded. In this implementation, asserts catch overflow in the integer
+ * part and similar (very, very) unlikely events. In reality, of course, gmp's
+ * random number engine has a finite internal state (19937 bits in the case of
+ * the MT19937 method). This means that these unlikely events in fact won't
+ * occur. If the asserts are triggered, then this is an indication that the
+ * random number engine is defective. (Even if a hardware random number
+ * generator were used, the most likely explanation for the triggering of the
+ * asserts would be that the hardware generator was broken.)

+ * we save on some bit shuffling when formed the mpz to be converted to an

Assume all special cases have been eliminated before.
In the extended exponent range, overflows/underflows are not possible.
Assume x > 0, or x < 0 and k odd.
+ Also assume |x| <> 1 because log(1) = 0, which does not have an exponent
+ and would yield a failure in the error bound computation. A priori, this
+ constraint is quite artificial because if |x| is close enough to 1, then
+ the exponent of log|x| does not need to be used (in the code, err would
+ be 1 in such a domain). So this constraint |x| <> 1 could be avoided in
+ the code. However, this is an exact case easy to detect, so that such a
+ change would be useless. Values very close to 1 are not an issue, since
+ an underflow is not possible before the MPFR_GET_EXP.

+ with application to computational geometry, Numerical Algorithms,
+ volume 37, number 1-4, pages 101--112, 2004.
+sorting is not necessary here. It is not done because in the most common
+cases (where big cancellations are rare), it would take time and be
+useless. However the lack of sorting increases the worst case complexity.
+For instance, consider many inputs that cancel one another (two by two).
+One would need n/2 iterations, where each iteration reads the exponent
+of each input, therefore n*n/2 read operations. Using a worst-case sort
+in O(n log n) could give a O(n log n) worst-case complexity. As we don't
+want to slow down the most common cases, this could be done at the 3rd
+iteration. But are there practical applications which would be used as
+tests?
+
+Note: see the following paper and its references:
+http://www.eecs.berkeley.edu/~hdnguyen/public/papers/ARITH21_Fast_Sum.pdf

+ *
+ * Notes:
+ * - minexp is also the exponent of the least significant bit of the
+ * accumulator;
+ * - the temporary area must be large enough to hold a shifted input
+ * block, and the value of ts is used only when the full assertions
+ * are checked (i.e. with the --enable-assert configure option), to
+ * check that a buffer overflow doesn't occur;

+/* The mpfr_urandom() function is implemented in the following way,
+ so that the exact number (the random value to be rounded) and the
+ final status of the random generator do not depend on the current
+ exponent range and on the rounding mode. However, they depend on
+ the target precision: from the same state of the random generator,
+ if the precision of the destination is changed, then the value may
+ be completely different (and the state of the random generator is
+ different too).
1. One determines the exponent exp: 0 with probability 1/2, -1 with
probability 1/4, -2 with probability 1/8, etc.
2. One draws a 1-ulp interval ]a,b[ containing the exact result (the
interval can be regarded as open since it has the same measure as
the closed interval).
+ One also draws the rounding bit. This is currently done with a
+ separate call to mpfr_rand_raw(), but it should be better to draw
+ the rounding bit as part of the significand; there is space for it
+ since the MSB is always 1.
3. Rounding is done. For the directed rounding modes, the rounded value
is uniquely determined. For rounding to nearest, ]a,m[ and ]m,b[,
where m = (a+b)/2, have the same measure, so that one gets a or b
with equal probabilities.
- Note: Only low-level functions are used (except just before a "return"),
