Write Floating-Point Literals with an exponent : Float Point Data Type « Data Type « Java Tutorial

Write the number as a decimal value followed by an E, or an e.

  1. Floating-point literals are of type double by default.
  2. To specify a value of type float, you append an f, or an F.
public class MainClass{

  public static void main(String[] arg){
     double f1 = 1.496E8;
     double f2 = 9.0E-28; 

     System.out.println(f2 + f1);
