Syntax

Math.getExponent(double d) has the following syntax.

public static int getExponent(double d)

Example

In the following code shows how to use Math.getExponent(double d) method.

// ww w  .ja  v  a  2s.c om

public class Main {

   public static void main(String[] args) {

      double x = 123456.7;
      double y = -123.45;

      // print the unbiased exponent of them
      System.out.println("Math.getExponent(" + x + ")=" + Math.getExponent(x));
      System.out.println("Math.getExponent(" + y + ")=" + Math.getExponent(y));
      System.out.println("Math.getExponent(0)=" + Math.getExponent(0));


   }
}

The code above generates the following result.
