## Detailed Description

Provides GLSL exponential functions.

These all operate component-wise. The description is per component.

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

## ◆ exp()

 GLM_FUNC_DECL vec glm::exp ( vec< L, T, Q > const & v )

Returns the natural exponentiation of x, i.e., e^x.

Parameters
 v exp function is defined for input values of v defined in the range (inf-, inf+) in the limit of the type qualifier.
Template Parameters
 L An integer between 1 and 4 included that qualify the dimension of the vector. T Floating-point scalar types.

## ◆ exp2()

 GLM_FUNC_DECL vec glm::exp2 ( vec< L, T, Q > const & v )

Returns 2 raised to the v power.

Parameters
 v exp2 function is defined for input values of v defined in the range (inf-, inf+) in the limit of the type qualifier.
Template Parameters
 L An integer between 1 and 4 included that qualify the dimension of the vector. T Floating-point scalar types.

## ◆ inversesqrt()

 GLM_FUNC_DECL vec glm::inversesqrt ( vec< L, T, Q > const & v )

Returns the reciprocal of the positive square root of v.

Parameters
 v inversesqrt function is defined for input values of v defined in the range [0, inf+) in the limit of the type qualifier.
Template Parameters
 L An integer between 1 and 4 included that qualify the dimension of the vector. T Floating-point scalar types.

## ◆ log()

 GLM_FUNC_DECL vec glm::log ( vec< L, T, Q > const & v )

Returns the natural logarithm of v, i.e., returns the value y which satisfies the equation x = e^y.

Results are undefined if v <= 0.

Parameters
 v log function is defined for input values of v defined in the range (0, inf+) in the limit of the type qualifier.
Template Parameters
 L An integer between 1 and 4 included that qualify the dimension of the vector. T Floating-point scalar types.

## ◆ log2()

 GLM_FUNC_DECL vec glm::log2 ( vec< L, T, Q > const & v )

Returns the base 2 log of x, i.e., returns the value y, which satisfies the equation x = 2 ^ y.

Parameters
 v log2 function is defined for input values of v defined in the range (0, inf+) in the limit of the type qualifier.
Template Parameters
 L An integer between 1 and 4 included that qualify the dimension of the vector. T Floating-point scalar types.

## ◆ pow()

 GLM_FUNC_DECL vec glm::pow ( vec< L, T, Q > const & base, vec< L, T, Q > const & exponent )

Returns 'base' raised to the power 'exponent'.

Parameters
 base Floating point value. pow function is defined for input values of 'base' defined in the range (inf-, inf+) in the limit of the type qualifier. exponent Floating point value representing the 'exponent'.

## ◆ sqrt()

 GLM_FUNC_DECL vec glm::sqrt ( vec< L, T, Q > const & v )

Returns the positive square root of v.

Parameters
 v sqrt function is defined for input values of v defined in the range [0, inf+) in the limit of the type qualifier.
Template Parameters
 L An integer between 1 and 4 included that qualify the dimension of the vector. T Floating-point scalar types.
