Compute the natural logarithm of 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 double-precision floating point values, use SDL_logf 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.
