typedef signed int | sint

## Functions

template<typename genType >
genType | factorial (genType const &x)
unsigned int | floor_log2 (unsigned int x)
template<typename genIUType >
genIUType | log2 (genIUType const &x)
int | mod (int x, int y)
uint | mod (uint x, uint y)
uint | nlz (uint x)
int | pow (int x, int y)
uint | pow (uint x, uint y)

## Detailed Description

Add support for integer for core functions.

<glm/gtx/integer.hpp> need to be included to use these functionalities.
