SDL_expf - Man Page

Defined in SDL3/SDL_stdinc.h

#include "SDL3/SDL.h"

float SDL_expf(float x);

The definition of y=exp(x) is y=e^x , 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.

x

floating point value.

Returns value of e^x .

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
