## 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.

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

GLM_EXT_vector_relational

## ◆ all()

 GLM_FUNC_DECL GLM_CONSTEXPR 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.
GLSL all man page
GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

## ◆ any()

 GLM_FUNC_DECL GLM_CONSTEXPR 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.
GLSL any man page
GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

## ◆ equal()

 GLM_FUNC_DECL GLM_CONSTEXPR vec 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
 L An integer between 1 and 4 included that qualify the dimension of the vector. T A floating-point, integer or bool scalar type.
GLSL equal man page
GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

## ◆ greaterThan()

 GLM_FUNC_DECL GLM_CONSTEXPR vec 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
 L An integer between 1 and 4 included that qualify the dimension of the vector. T A floating-point or integer scalar type.
GLSL greaterThan man page
GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

## ◆ greaterThanEqual()

 GLM_FUNC_DECL GLM_CONSTEXPR vec 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.
GLSL greaterThanEqual man page
GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

## ◆ lessThan()

 GLM_FUNC_DECL GLM_CONSTEXPR vec 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
 L An integer between 1 and 4 included that qualify the dimension of the vector. T A floating-point or integer scalar type.
GLSL lessThan man page
GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

## ◆ lessThanEqual()

 GLM_FUNC_DECL GLM_CONSTEXPR vec 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.
GLSL lessThanEqual man page
GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

## ◆ not_()

 GLM_FUNC_DECL GLM_CONSTEXPR vec 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.
GLSL not man page
GLSL 4.20.8 specification, section 8.7 Vector Relational Functions

## ◆ notEqual()

 GLM_FUNC_DECL GLM_CONSTEXPR vec glm::notEqual ( 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, integer or bool scalar type.
