Java cbrt() method with Examples
The java.lang.Math.cbrt(double a) returns the cube root of a double value. For positive finite x, cbrt(-x) == -cbrt(x); that is, the cube root of a negative value is the negative of the cube root of that value's magnitude. Special cases −
If the argument is NaN, then the result is NaN.
If the argument is infinite, then the result is an infinity with the same sign as the argument.
If the argument is zero, then the result is a zero with the same sign as the argument.
Example
Following is an example to implement the cbrt() method in Java −
import java.lang.*;
public class Example {
public static void main(String[] args) {
// get two double numbers
double x = 125;
double y = 10;
// print the cube roots of three numbers
System.out.println("Math.cbrt(" + x + ")=" + Math.cbrt(x));
System.out.println("Math.cbrt(" + y + ")=" + Math.cbrt(y));
System.out.println("Math.cbrt(-27)=" + Math.cbrt(-27));
}
}Output
Math.cbrt(125.0)=5.0 Math.cbrt(10.0)=2.154434690031884 Math.cbrt(-27)=-3.0
Example
Let us see another example −
import java.lang.*;
public class Example {
public static void main(String[] args) {
// get two double numbers
double x = 0.0;
double y = -343.0;
// print the cube roots of three numbers
System.out.println("Math.cbrt(" + x + ")=" + Math.cbrt(x));
System.out.println("Math.cbrt(" + y + ")=" + Math.cbrt(y));
}
}Output
Math.cbrt(0.0)=0.0 Math.cbrt(-343.0)=-7.0
