NAME
libzahl - big integer library
ETYMOLOGY
The bold uppercase Z which represents the set of
all integers is derived from the german word 'zahlen',
whose singular is 'zahl'.
DESCRIPTION
libzahl is a C library for arbitrary size integers,
that aims to be usable for rubust programs, and be
fast.
libzahl will accomplish this by using long jumps
when an error is detected, rather than letting the
caller also perform a check. This shall make the
code in the user program cleaner too. libzahl will
use dedicated temporary bitnum integers whether
possible, and necessary, for its internal calculations.
libzahl will not deallocate allocations, but rather
cache them for reuse.
With the exception of functions working with strings,
all output parameters are before the input parameters.
RATIONALE
GMP MP cannot be used for rubust programs. LibTomMath
is too slow, probably because of all memory allocations,
and has an nonintuitive API. Hebimath is promising, but
I think it can be done better.
