NAME

SDL_expf - Compute the exponential of x .

HEADER FILE

Defined in SDL3/SDL_stdinc.h

SYNOPSIS

#include "SDL3/SDL.h"

float SDL_expf(float x);

DESCRIPTION

The definition of y = exp(x) is y = eˆx , where e is the base of the natural logarithm. The inverse is the natural logarithm,

SDL_logf .

Domain: -INF <= x <= INF Range: 0 <= y <= INF The output will overflow if exp(x) is too large to be represented.

This function operates on single-precision floating point values, use

SDL_exp
for double-precision floats.

This function may use a different approximation across different versions, platforms and configurations. i.e, it can return a different value given the same input on different machines or operating systems, or if SDL is updated.

FUNCTION PARAMETERS

floating point value.

RETURN VALUE

Returns value of eˆx .

THREAD SAFETY

It is safe to call this function from any thread.

AVAILABILITY

This function is available since SDL 3.2.0.
