SDL_logf - Man Page

#include <SDL3/SDL_stdinc.h>

float SDL_logf(float x);

Domain: 0 < x <= INF

Range: -INF <= y <= INF

It is an error for x to be less than or equal to 0.

This function operates on single-precision floating point values, use SDL_log 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. Must be greater than 0.

Returns the natural logarithm of x.

It is safe to call this function from any thread.

This function is available since SDL 3.2.0.
