Function pow

Calculates the power of x to y, x ^ y. Matrix exponentiation is supported for square matrices x, and positive integer exponents y.

For cubic roots of negative numbers, the function returns the principal root by default. In order to let the function return the real root, math.js can be configured with math.config({predictable: true}). To retrieve all cubic roots of a value, use math.cbrt(x, true).

Syntax

math.pow(x, y)

Parameters

Parameter	Type	Description
x	number | BigNumber | Complex | Array | Matrix	The base
y	number | BigNumber | Complex	The exponent

Returns

Type	Description
number | BigNumber | Complex | Array | Matrix	The value of x to the power y

Examples

math.pow(2, 3);               // returns number 8

var a = math.complex(2, 3);
math.pow(a, 2)                // returns Complex -5 + 12i

var b = [[1, 2], [4, 3]];
math.pow(b, 2);               // returns Array [[9, 8], [16, 17]]
