In this chapter, you learned that although a double and a decimal both hold floating-point numbers, a double can hold a larger value. Write a C# program named DoubleDecimalTest that declares and displays two variables—a double and a decimal. Experiment by assigning the same constant value to each variable so that the assignment to the double is legal but the assignment to the decimal is not.

The DoubleDecimalTest class is as follows:

using System;

class DoubleDecimalTest {

 static void Main() {

     double doubleNum = 173737388856632566321737373676D;  

    decimal decimalNum = 173737388856632566321737373676M;

   Console.WriteLine(doubleNum);

   Console.WriteLine(decimalNum);  } }

Program to test double and decimal variables in C#

This declares and initializes double variable doubleNum

     double doubleNum = 173737388856632566321737373676D;

This declares and initializes double variable decimalNum (using the same value as doubleNum)

     decimal decimalNum = 173737388856632566321737373676M;

This prints doubleNum

   Console.WriteLine(doubleNum);

This prints decimalNum

   Console.WriteLine(decimalNum);

Unless the decimal variable is commented out or the value is reduced to a reasonable range, the program will not compile without error.
