StrictMath cbrt() Method in Java

The java.lang.StrictMath.cbrt() is an inbuilt method in Java which is used to return the cube root of a given double value. The method shows three special results:

  • The result is a zero with the same sign as the argument when the given argument is zero.
  • The result is infinity with the same sign of argument when the argument is infinite.
  • The result is NaN when the given argument is NaN.

Syntax:

public static double cbrt(double num)

Parameters: This method accepts one parameter num which is of double type whose cube root is required to be found.



Return Value : The method returns the cube root of num.

    }
}
