Cross-platform fixed point maths library with a support of macro templates written fully on C.

Russian/Русский

Description

This library provides you with type-generic functions that perform fixed point calculations. All operatable types are standard fixed size integers (see inttypes.h). Due to macro templates implementation there is a possibility of using this library with platform- or compiler-dependent integers (for example, with __int128_t, which is not supported by default). The format of numbers (number of bits in fractional part) is specified in runtime by the user.

Documentation
