Aarith: An Arbitrary Precision Number Library

Linux Build Status Documentation Status

Aarith is a header-only, arbitrary precision number library for C++. It is intended to be used as a drop-in replacement of the native data types.

Aarith currently supports

  • IEEE 754 like floating-point numbers of arbitrary bit-width for both, the exponent and the mantissa

  • Two’s complement integers of arbitrary bit-width (signed and unsigned)
