SDL_exp - Man Page

Compute the exponential of x .

Header File

Defined in SDL3/SDL_stdinc.h

Synopsis

#include "SDL3/SDL.h"

double SDL_exp(double x);

Description

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_log .

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 double-precision floating point values, use

SDL_expf
for single-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.

Availability

This function is available since SDL 3.2.0.
