Math.pow()
The Math.pow() returns the base to the exponent power.
Syntax
Math.pow(base, exponent);Parameters
base
The base number
exponent
The exponent with which to raise the base number.
Description
.pow() is a static method of the Math object, so you must always use it as Math.pow()
Examples
// Simple exponents
Math.pow(2, 2); // 4
Math.pow(2, 3); // 8
Math.pow(2, 10); // 1024
//Fractional exponents
Math.pow(9, 0.5); // 3 (the square root of 9)
Math.pow(24, 1/3); // 8 (the cubed root of 24)
//Signed exponents
Math.pow(5, -2); // .04 (1/25)
//Signed bases
Math.pow(-5, 2); // 25 (squares are positive)
Math.pow(-5, 3); // -125 (cubes can be negative)
Math.pow(-5, 0.5); // NaN because negative numbers don't have a real square root
//Due to limits in the precision of floating point numbers,
//a negative base with a fractional exponent will always return NaN
Math.pow(-5, 1/2); // NaN
