Cube root of a negative number

Question

I\'m trying to find the cube root of a negative number but I get a NaN. Any help?

System.out.println(Math.pow(-8, 1.0 / 3.0));

Answer 1

The Java documentation for Math.pow states:

If the first argument is finite and less than zero [...] [and] if the second argument is finite and not an integer, then the result is NaN.

You could use Math.cbrt to get the cube root:

double result = Math.cbrt(-8.0);
