The java.lang.Math.cbrt () is used to return the cube root of a number.

Syntax

Parameter

Return

If the argument is positive or negative double value, this method will return the cube root of a given value.
If the argument is NaN, this method will return NaN.
If the argument is infinity, this method will return Infinity with same sign as the argument.
If the argument is positive or negative Zero, this method will return Zero with same sign as the argument.

Example 1

public class CbrtExample1
{
    public static void main(String[] args) 
    {
        double x = 729;
        //return the cube root of x
        System.out.println(Math.cbrt(x));
    }
}
