Java Math.signum(float f)
Syntax
Math.signum(float f) has the following syntax.
public static float signum(float f)
Example
In the following code shows how to use Math.signum(float f) method.
public class Main {
//from w w w . ja v a2 s . c om
public static void main(String[] args) {
float x = 12.34f;
float y = -4f;
// call signum for both floats and print the result
System.out.println("Math.signum(" + x + ")=" + Math.signum(x));
System.out.println("Math.signum(" + y + ")=" + Math.signum(y));
}
}
The code above generates the following result.
