NAME¶

SDL_log10 - Compute the base-10 logarithm of x.

SYNOPSIS¶

#include <SDL3/SDL_stdinc.h>

double SDL_log10(double x);

DESCRIPTION¶

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 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.

FUNCTION PARAMETERS¶

x

floating point value. Must be greater than 0.

RETURN VALUE¶

Returns the logarithm of x.

THREAD SAFETY¶

It is safe to call this function from any thread.

AVAILABILITY¶

This function is available since SDL 3.2.0.
