SDL_expf3
Compute the exponential of x .
Usage
#include "SDL3/SDL.h"
float SDL_expf(float x);
Header file
Defined in SDL3/SDL_stdinc.h
Overview
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.
Function parameters
- x
-
floating point value.
Return value
Returns value of e^x .
Thread safety
It is safe to call this function from any thread.
