Normal:
Abnormal:
f
y
#include <mathf.h>
float x, y, ret;
A domain error occurs if x is 0.0 and y is 0.0 or less, or if x is negative and y
is not an integer.
#include <mathf.h>
float f, ret;
A domain error occurs if f is negative.
ret=powf(x, y);
ret=sqrtf(x, y);
Value of x raised to the power y
In case of domain error: Returns not-a-number.
Value to be raised to a power
Power value
Positive square root of f
In case of domain error: Returns not-a-number.
