The MiniFP package
Purpose:
minifp.sty defines macros for calculating with decimal real numbers.
It provides 8 decimal digits before and after the decimal point.
Minifp also provides a stack-based "assembly" language for writing
"programs".
In its basic form, minifp makes only simple operations available. To
get additional operations (sine, cosine, angle, square root, log and
exp), the file mfpextra.tex is provided.
Minifp should work in both LaTeX and plainTeX.
This is version 0.95. It should work reasonably well, barring any
bugs, but I expect to spend some time fine-tuning it before calling it
version 1.0.
License:
All files of the minifp distribution (listed below) may be distributed
and/or modified under the conditions of the LaTeX Project Public
License, either version 1.3c of this license or (at your option) any
later version. The latest version of this license is in
http://www.latex-project.org/lppl.txt
and version 1.3c or later is part of all distributions of LaTeX
version 2008/12/01 or later.
While every effort has been made to make minifp useful, it comes with
no warranty, expressed or implied.
Usage:
You can use minifp as a LaTeX package with
\usepackage{minifp}
or use it in plain TeX with
\input minifp.sty
You can access the extra commands from mfpextra.tex by issuing the
command
\MFPloadextra
after minifp.sty has been loaded.
Installation:
To install minifp, obtain minifp.tds.zip from CTAN and unzip it in any
TDS-compliant texmf tree.
Or, in the presence of minifp.dtx, run tex or latex on minifp.ins to
unpack the files minifp.sty and mfpextra.tex. Copy those files to some
place where both tex and latex can find them. For example, in a TDS
compliant system, the directory /tex/generic/minifp/ under one of your
TEXMF root directories.
The documentation is provided in minifp.pdf. Put minifp.pdf (and this
README and the files test*.tex, if you wish) wherever documentation of
packages is kept. For example, in the directory /doc/generic/minifp/
under one of your TEXMF root directories.
If you wish to regenerate the documentation, run latex (or pdflatex)
on minifp.dtx three times and then
makeindex -s gind.ist -o minifp.ind minifp.idx
and then (pdf)latex again on minifp.dtx.
Manifest:
These, together with the files minifp.sty and mfpextra.tex (generated
by tex-ing minifp.ins), constitute the minifp distribution to which the
license applies:
minifp.dtx Contains minifp.sty and mfpextra.tex
minifp.ins The unpacking script: run tex or latex on it.
It reads in minifp.dtx and produces the files
minifp.sty and mfpextra.tex
minifp.pdf Documentation
test1.tex A suite of tests, including error messages (plain TeX)
test2.tex More tests, including long tests of speed (plain TeX)
README This file.
This distribution, the latest updates, and possibly some past
versions, should also be available at my web site:
<http://comp.uark.edu/~luecking/tex/tex.html>.
History:
Version 0.95: More testing. Changed square root of negative from an
error to a warning. Documentation updated. Now mfpextra
checks for minifp.sty and inputs it if needed.
Version 0.94: Improved accuracy of log, sin and sqrt.
Version 0.93: Corrected mistyped data for logarithm.
Fixed bugs in degree/radian conversions.
Version 0.92: Corrected sign of floor and ceiling. Corrected
occasional minus sign in front of 0.0 for sin or cos.
Version 0.9 : angle: near maximum accuracy, at some cost to speed.
Version 0.8 : exp: now more accurate for many cases.
Version 0.7 : sqrt: now exact when possible and much more accurate.
Version 0.6 : Added angle to mfpextra. Changed package name to minifp.
Version 0.5 : Added sqrt, deg, rad to mfpextra.
Version 0.4 : Added log, exp, pow to mfpextra.
Version 0.3 : Added mfpextra.tex, defines sin and cos.
Version 0.2 : Added macros for printing, formatting the results.
Version 0.1 : First working set of macros. Package named mfp.sty.
