sdlExpf function

double sdlExpf(
  1. double x
)

Compute the exponential of x.

The definition of y = exp(x) is y = e^x, where e is the base of the natural logarithm. The inverse is the natural logarithm, SDL_logf.

Domain: -INF <= x <= INF

Range: 0 <= y <= INF

The output will overflow if exp(x) is too large to be represented.

This function operates on single-precision floating point values, use SDL_exp 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.

\param x floating point value. \returns value of e^x.

\threadsafety It is safe to call this function from any thread.

\since This function is available since SDL 3.1.3.

Implementation

  final sdlExpfLookupFunction = libSdl3.lookupFunction<Float Function(Float x),
      double Function(double x)>('SDL_expf');
  return sdlExpfLookupFunction(x);
