sdlExpf function
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.
