The Math.cbrt() method returns the cube root of a double value.


Math.cbrt(double num)

The .cbrt() method will return the cube root of num. The value of num can be any real number. Edge cases for this method include:

  • If the argument is NaN, the return value will be NaN.
  • If the argument is ±infinity, the return value will be ±infinity.


Here is an example using the Math.cbrt() method:

public class Main {
public static void main(String[] args) {
double a = 27.0;
System.out.println("Math.cbrt(" + a + ") returns: " + Math.cbrt(a));
double b = -8.0;
System.out.println("Math.cbrt(" + b + ") returns: " + Math.cbrt(b));

This will result in the following output:

Math.cbrt(27.0) returns: 3.0
Math.cbrt(-8.0) returns: -2.0
