This provides a wrapper that allows to define pgfmath functions using the
expl3 FPU (which's LaTeX2e document-level package is called xfp) for the
calculations. Each input argument is parsed by pgfmath to normalize it to a
form that xfp understands.
The only place where version numbers and dates are guaranteed to be correct in
the repository is in the l3build configuration file build.lua. If it is
important to you that the files created have the correct version and date, you
should run l3build tag before any other build-related task.
pgfmath-xfp utilizes the l3build system. You can run l3build unpack to
extract the package pgfmath-xfp.sty into the directory build/unpacked/.
If you want to build the documentation run l3build doc, the resulting PDF will
be in the main directory. Running l3build install will put pgfmath-xfp.sty
in your TEXMFHOME, l3build uninstall will remove it. l3build should be
contained in any recent LaTeX installation.
You can run the checks from the folder testfiles/ by running l3build check
to test whether the version you got has any regressions.
Of course you can also build everything manually. pdftex pgfmath-xfp.dtx will
generate the code files, pdflatex pgfmath-xfp.dtx will create the
documentation, but you'll have to run that at least twice, and if you want an
index you'll also have to run makeindex -s gind.ist -o pgfmath-xfp.ind pgfmath-xfp.idx and then rerun pdflatex. Building the files manually will
create quite a few auxiliary files in the main directory.
