24    ECMA Section:       15.8.2.8  Math.exp(x)
25    Description:        return an approximation to the exponential function of
26                        the argument (e raised to the power of the argument)
27                        special cases:
28                        -   if x is NaN         return NaN
29                        -   if x is 0           return 1
30                        -   if x is -0          return 1
31                        -   if x is Infinity    return Infinity
32                        -   if x is -Infinity   return 0
