YACBNL

yet another c big number library YACBiNuLi, "yak-binewly"

a (toy) single-header lightweight C arbitrary precision library using uint8_t* arrays.

the library isn't written as a single header, but is built into yacbnl.full.h; just include that. (see build.sh).

to compile with slower string operations for primitive conversions rather than floating point math, use -DPREFER_CHAR_CONV on the command line or #define PREFER_CHAR_CONV before the #include "yacbnl.h".

written in C11, builds as C++ >= 11.

you should probably use boost, and in C, you should probably use GMP because this is a toy.

example premake project for downstream projects:

project "yacbnl"
  kind "staticlib"
  files { "deps/yacbnl/yacbnl.min.c" }
  links { "m" }

the tests need the excellent criterion testing framework http://github.com/snaipe/criterion

list of generated files:

  • min/yacbnl.full.c
