## Detailed Description

Include <glm/vector_relational.hpp> to use these core features.

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

GLM_FUNC_DECL bool glm::all | ( | vec< L, bool, Q > const & | v | ) |

Returns true if all components of x are true.

Template Parameters

  L | An integer between 1 and 4 included that qualify the dimension of the vector.

GLM_FUNC_DECL bool glm::any | ( | vec< L, bool, Q > const & | v | ) |

Returns true if any component of x is true.

Template Parameters

  L | An integer between 1 and 4 included that qualify the dimension of the vector.

GLM_FUNC_DECL vec<L, bool, Q> glm::equal | ( | vec< L, T, Q > const & | x,
|  | vec< L, T, Q > const & | y
| ) |  |

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

Template Parameters

GLM_FUNC_DECL vec<L, bool, Q> glm::greaterThan | ( | vec< L, T, Q > const & | x,
|  | vec< L, T, Q > const & | y
| ) |  |

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

Template Parameters

GLM_FUNC_DECL vec<L, bool, Q> glm::greaterThanEqual | ( | vec< L, T, Q > const & | x,
|  | vec< L, T, Q > const & | y
| ) |  |

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

Template Parameters

  L | An integer between 1 and 4 included that qualify the dimension of the vector.
  T | A floating-point or integer scalar type.

GLM_FUNC_DECL vec<L, bool, Q> glm::lessThan | ( | vec< L, T, Q > const & | x,
|  | vec< L, T, Q > const & | y
| ) |  |

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

Template Parameters

GLM_FUNC_DECL vec<L, bool, Q> glm::lessThanEqual | ( | vec< L, T, Q > const & | x,
|  | vec< L, T, Q > const & | y
| ) |  |

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

Template Parameters

  L | An integer between 1 and 4 included that qualify the dimension of the vector.
  T | A floating-point or integer scalar type.

GLM_FUNC_DECL vec<L, bool, Q> glm::not_ | ( | vec< L, bool, Q > 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

  L | An integer between 1 and 4 included that qualify the dimension of the vector.

|  | vec< L, T, Q > const & | y
| ) |  |

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

Template Parameters

  L | An integer between 1 and 4 included that qualify the dimension of the vector.
