Availability
JavaScript 1.0; JScript 1.0; ECMAScript v1
Synopsis
Math.pow(x, y)
Arguments
 x

The number to be raised to a power.
 y

The power that x is to be raised to.
Returns
x to the power of
y,
x^{y}.
Description
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
floatingpoint overflow and return a value of
Infinity.
