## exp
expf

Syntax

    #include <math.h>
    double exp(double x);
    float expf(float x);

Arguments

- x is the exponent power you want

Return Value
An exponent to the x power
Explanation
It calculates an exponent to the x power using this formula:

    exp(x) = 1 + x + x^2/2! + x^3/3! +
       x^4/4! + ... (-1<= x <=1)
    exp(nk*log2+xx) = exp(nk * log2) *exp (xx)
          = 2^nk * exp (xx)

Note
This standard function comes with NuSystem.
