Math.cbrt()

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

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

cbrt(x)

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