Using the recurrence $x_n=(x_{n-55}-x_{n-31})\bmod 2^{28}$, +we generate batches of 55 new $x_n$'s at a time by calling |new_randoms|. +The global variable |j_random| tells which element has most recently +been consumed. + +@<Glob...@>= +@!randoms:array[0..54] of integer; {the last 55 random values generated} +@!j_random:0..54; {the number of unused |randoms|} +@!random_seed:scaled; {the default random seed} + +@ A small bit of metafont is needed. + +@d fraction_half==@'1000000000 {$2^{27}$, represents 0.50000000} +@d fraction_one==@'2000000000 {$2^{28}$, represents 1.00000000} +@d fraction_four==@'10000000000 {$2^{30}$, represents 4.00000000} +@d el_gordo == @'17777777777 {$2^{31}-1$, the largest value that \MP\ likes} +@d halfp(#)==(#) div 2 +@d double(#) == #:=#+# {multiply a variable by two} + +@ The |make_frac| routine produces the |fraction| equivalent of +|p/q|, given integers |p| and~|q|; it computes the integer +$f=\lfloor2^{28}p/q+{1\over2}\rfloor$, when $p$ and $q$ are +positive. If |p| and |q| are both of the same scaled type |t|, +the ``type relation'' |make_frac(t,t)=fraction| is valid; +and it's also possible to use the subroutine ``backwards,'' using +the relation |make_frac(t,fraction)=t| between scaled types. + +If the result would have magnitude $2^{31}$ or more, |make_frac| +sets |arith_error:=true|. Most of \MP's internal computations have +been designed to avoid this sort of error. + +If this subroutine were programmed in assembly language on a typical +machine, we could simply compute |(@t$2^{28}$@>*p)div q|, since a +double-precision product can often be input to a fixed-point division +instruction. But when we are restricted to \PASCAL\ arithmetic it +is necessary either to resort to multiple-precision maneuvering +or to use a simple but slow iteration. The multiple-precision technique +would be about three times faster than the code adopted here, but it +would be comparatively long and tricky, involving about sixteen +additional multiplications and divisions. + +This operation is part of \MP's ``inner loop''; indeed, it will +consume nearly 10\pct! of the running time (exclusive of input and output) +if the code below is left unchanged. A machine-dependent recoding +will therefore make \MP\ run faster. The present implementation +is highly portable, but slow; it avoids multiplication and division +except in the initial stage. System wizards should be careful to +replace it with a routine that is guaranteed to produce identical +results in all cases. +@^system dependencies@> + +As noted below, a few more routines should also be replaced by machine-dependent +code, for efficiency.
