## Detailed Description

Include <glm/gtc/integer.hpp> to use the features of this extension.

Allow to perform bit operations on integer values

## Function Documentation

## ◆ iround()

GLM_FUNC_DECL vec<L, int, Q> glm::iround | ( | vec< L, T, Q > 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.

## ◆ log2()

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.

## ◆ uround()

GLM_FUNC_DECL vec<L, uint, Q> glm::uround | ( | vec< L, T, Q > 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.
