In the previous article, I have explained about expressing the floating-point and double literals in standard and scientific formats.

In this article, I am going to explain about representing floating-point and double literals in different ways.

Java for Testers – Different ways of representing floating-point and double literals

Floating-point and double literals can be representing in the following different ways:

1) Floating-point literals can be represented by adding a small letter or capital letter at the end of the literal value as shown below

float a = 123.456f

float a = 123.456F

2) Double literals can be represented by adding a small letter or capital letter or no letter at the end of the literal value as shown below

double a = 123.456;

double a = 123.456d;

double a = 123.456D;

Below are the screenshots for the practical demonstration of the above different possibilities:

Representation#1

float double representations - f

Representation#2 

float double representations - F2

Representation#3

float double representations - nothing

Representation#4

float double representations - d

Representation#5

float double representations - D2

Here conclude this article on assigning the different ways of representing floating-point and double data type literals.

In the next article, I will explain different Type Conversions in Java.
