SDL_log10

Header File

Defined in <SDL3/SDL_stdinc.h>

Syntax

double SDL_log10(double x);

Function Parameters

double x floating point value. Must be greater than 0.

Return Value

(double) Returns the logarithm of x.

Remarks

Domain: 0 < x <= INF

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

This function operates on double-precision floating point values, use SDL_log10f 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.

Thread Safety

It is safe to call this function from any thread.
