SDL_exp - Compute the exponential of x .
Contents
Availability
This function is available since SDL 3.2.0.
Description
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_log .
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 double-precision floating point values, use
SDL_expf
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.
Header File
