   ECMA Section:       15.8.2.8  Math.exp(x)
   Description:        return an approximation to the exponential function of
   the argument (e raised to the power of the argument)
   special cases:
   -   if x is NaN         return NaN
   -   if x is 0           return 1
   -   if x is -0          return 1
   -   if x is Infinity    return Infinity
   -   if x is -Infinity   return 0
