Math.pow(x, y)
The number or numeric expression to be raised to a power.
The power that x is to be raised to.
x to the power of y, xy
Math.pow() raises its first argument to the power of its second argument and returns the result.
Any values of x and y may be passed to Math.pow(). However, if the result is an imaginary or complex number, then Math.pow() returns zero. In practice, this means that if x is negative, then 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.
