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

x	The values of the argument must be greater or equal to zero.

Template Parameters

T	floating point scalar types.

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_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

genIUType Integer-point scalar or vector types.

Parameters

x	The values of the argument must be greater or equal to zero.
