Function SDL_expf
pub unsafe extern "C" fn SDL_expf(x: f32) -> f32
Available on crate feature
dep_sdl3
only.Expand description
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.
§Parameters
x
: floating point value.
§Return value
Returns value of e^x
.
§Thread safety
It is safe to call this function from any thread.
§Availability
This function is available since SDL 3.2.0.
