      1 NAME
      2 	libzahl - Big integer library
      3 
      4 ETYMOLOGY
      5 	The bold uppercase 'Z' which represents the set of
      6 	all integers is derived from the german word 'Zahlen',
      7 	whose singular is 'Zahl'.
      8 
      9 DESCRIPTION
     10 	libzahl is a C library for arbitrary size integers,
     11 	that aims to be usable for robust programs, and be
     12 	fast.
     13 
     14 	libzahl will accomplish this by using long jumps
     15 	when an error is detected, rather than letting the
     16 	caller also perform a check. This shall make the
     17 	code in the user program cleaner too. libzahl will
     18 	use dedicated temporary bignum integers whether
     19 	possible, and necessary, for its internal calculations.
     20 	libzahl will not deallocate allocations, but rather
     21 	cache them for reuse.
     22 
     23 	With the exception of functions working with strings,
     24 	all output parameters are before the input parameters.
     25 
     26 RATIONALE
     27 	GMP MP cannot be used for robust programs. LibTomMath
     28 	is too slow, probably because of all memory allocations,
     29 	and has a nonintuitive API. TomsFastMath has an a
     30 	nonintuitive API, has limited precision (selected at
     31 	compile-time), and has limited functionality. All the
     32 	above are also bloated. Hebimath is promising, but I
     33 	think it can be done better.
     34 
     35 NOTES
     36 	libzahl is currently not thread-safe.
