Detailed Description

Allow to perform bit operations on integer values.

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

Function Documentation

GLM_FUNC_DECL vec<L, int, P> glm::iround ( vec< L, T, P > const &  x)

Returns a value equal to the nearest integer to x.

The fraction 0.5 will round in a direction chosen by the implementation, presumably the direction that is fastest.

Parameters
xThe values of the argument must be greater or equal to zero.
Template Parameters
Tfloating point scalar types.

GLM_GTC_integer
GLM_FUNC_DECL genIUType glm::log2 ( genIUType  x)

Returns the log2 of x for integer values.

Can be reliably using to compute mipmap count from the texture size.

GLM_GTC_integer
GLM_FUNC_DECL genIUType glm::mod ( genIUType  x,
genIUType  y 
)

Modulus.

Returns x % y for each component in x using the floating point value y.

Template Parameters
genIUTypeInteger-point scalar or vector types.
