## Detailed Description

Relational and equality operators (<, <=, >, >=, ==, !=) are defined to operate on scalars and produce scalar Boolean results.

For vector results, use the following built-in functions.

In all cases, the sizes of all the input and return vectors for any particular call must match.

## Function Documentation

bool glm::all | ( | vecType< bool > const & | v | ) |

Returns true if all components of x are true.

Template Parameters

  vecType | Boolean vector types.

bool glm::any | ( | vecType< bool > const & | v | ) |

Returns true if any component of x is true.

Template Parameters

  vecType | Boolean vector types.

vecType::bool_type glm::equal | ( | vecType const & | x,
|  | vecType const & | y
| ) |  |

Returns the component-wise comparison of result x == y.

Template Parameters

  vecType | Floating-point, integer or boolean vector types.

vecType::bool_type glm::greaterThan | ( | vecType const & | x,
|  | vecType const & | y
| ) |  |

Returns the component-wise comparison of result x > y.

Template Parameters

  vecType | Floating-point or integer vector types.

vecType::bool_type glm::greaterThanEqual | ( | vecType const & | x,
|  | vecType const & | y
| ) |  |

Returns the component-wise comparison of result x >= y.

Template Parameters

  vecType | Floating-point or integer vector types.

  GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

vecType::bool_type glm::lessThan | ( | vecType const & | x,
|  | vecType const & | y
| ) |  |

Returns the component-wise comparison result of x < y.

Template Parameters

  vecType | Floating-point or integer vector types.

  GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

vecType::bool_type glm::lessThanEqual | ( | vecType const & | x,
|  | vecType const & | y
| ) |  |

Returns the component-wise comparison of result x <= y.

Template Parameters

  vecType | Floating-point or integer vector types.

vecType<bool> glm::not_ | ( | vecType< bool > const & | v | ) |

Returns the component-wise logical complement of x.

/!\ Because of language incompatibilities between C++ and GLSL, GLM defines the function not but not_ instead.

Template Parameters

  vecType | Boolean vector types.

vecType::bool_type glm::notEqual | ( | vecType const & | x,
|  | vecType const & | y
| ) |  |

Returns the component-wise comparison of result x != y.

Template Parameters

  vecType | Floating-point, integer or boolean vector types.
