Parameters:
Parameters:
Computes the exponential function of a floating-point number.
Exponential value of f
Breaks a floating-point number into a [0.5, 1.0)value and a power of 2.
If value is 0.0: 0.0
If value is not 0.0: Value of ret defined by ret * 2

int *e
The frexpf function breaks a value into a [0.5, 1.0) value and a power of 2. It
stores the resultant power-of-2 value in the area pointed to by e.
The frexpf function returns the return value ret in the range [0.5, 1.0) or as 0.0.
of ret are both 0.0.
