Header File

Syntax

Function Parameters

x	floating point value. Must be greater than 0.

Return Value

Returns the logarithm of x

Remarks

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_log10 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.

Version

This function is available since SDL 3.0.0.
