return the value of the first parameter raised to the power of the second
genType pow(genType x, genType y)x: Specify the value to raise to the power y.y: Specify the power to which to raise x.pow returns the value of x raised to the y power. i.e.,
$$
x^{y}
$$
Results are undefined if x < 0 or if x == 0 and y ≤ 0.
