The Math.cbrt() static method returns the cube root of a number. That is

π™ΌπšŠπšπš‘.πšŒπš‹πš›πš(𝚑)=x3=the unique y such that y3=x\mathtt{\operatorname{Math.cbrt}(x)} = \sqrt[3]{x} = \text{the unique } y \text{ such that } y3 = x

Syntax

Math.cbrt(x)

Parameters

Return value

The cube root of x.

Description

Because cbrt() is a static method of Math, you always use it as Math.cbrt(), rather than as a method of a Math object you created (Math is not a constructor).

Examples

Using Math.cbrt()

Math.cbrt(-Infinity); // -Infinity
Math.cbrt(-1); // -1
Math.cbrt(-0); // -0
Math.cbrt(0); // 0
Math.cbrt(1); // 1
Math.cbrt(2); // 1.2599210498948732
Math.cbrt(Infinity); // Infinity
