lavantien / biguint.h
Last active April 14, 2021 21:51
biguint - Simple Optimized Big Unsigned Integer Library
/*
Big Unsigned Integer Library (biguint).
Written by Tien La.
User can do anything with this library, since there, I don't have any responsibility about any damage that may occur.
For any question or suggestion, please email me at [email protected] or via Facebook: fb.com/cariyaputta
This library is mainly for demonstration but still quite optimized and pretty fast.
All functions in this library don't return value (except 'GMP' function), instead, they use references to speed things up.
The rule of these function is almost the same: first argument is the result of the function, except 'cmp' and 'wl'.
