Math.pow( ) computes
x to the power of
y. Any values of
x and y may be
passed to Math.pow( ). However,
if the result is an imaginary or complex number, Math.pow( ) returns NaN. In practice, this means that if
x is negative,
y should be a positive or negative
integer. Also, bear in mind that large exponents can easily cause
floating-point overflow and return a value of Infinity.
