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

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

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