libfixmath
This is a tried and tested cross platform fixed point maths library.
It has been used in projects such as: * Dingoo SDK * AstroLander (Included in Dingoo SDK) * FGL: Flatmush/Fixed-point Graphics Library
This library implements the math.h functions in fixed point (16.16) format, a subset of the currently supported functions are: * sin, cos, tan * asin, acos, atan, atan2 * sqrt, exp * mul, div * sadd, ssub, smul, sdiv (saturated arithmetic)
I related library libfixmatrix which utilises libfixmath for matrix operations can be found here: https://github.com/PetteriAimonen/libfixmatrix
