Question

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.

Answer 1

Answer:

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);  } }

Explanation:

Required

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.
