Write the number as a decimal value followed by an E, or an e.
Floating-point literals are of type double by default.
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(f1);
System.out.println(f2);
System.out.println(f2 + f1);
}
}
1.496E8
9.0E-28
