NAME¶

SDL_exp - Compute the exponential of x.

SYNOPSIS¶

#include <SDL3/SDL_stdinc.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.
