Math.cbrt()

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

$$\mathtt{\operatorname{Math.cbrt}(x)} = \sqrt[3]{x} = \text{the unique } y \text{ such that } y^3 = x$$

Math.cbrt(x)

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
