## 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 vecType<int, P> glm::iround | ( | vecType< 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.
  vecType | vector 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.

GLM_FUNC_DECL vecType< T, P > mod | ( | vecType< T, P > const & | x,
|  | T | y
| ) |  |

Modulus.

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