In this post, we are going to learn how to write a program to multiply two floating -point numbers in C# language

Code to multiply two floating-point numbers in C#

Multiply two floating-point numbers in C#

In this code, we are going to learn how to write a program to multiply two floating-point numbers using initialized variables in C# programming language

Program 1

// Calculate multiplication of two floating point numbers in C# program 
using System; 
public class Multiply_Float_Num { //Class declaration
    public static void Main(string[] args) { //main method
        float num1=15.34f; //declare and initialize variable for num1
        float num2=20.12f;  //declare and initialize variable for num2
        float mul=num1*num2; //Calculate multiplication of two numbers
        Console.WriteLine ("The multiplication of two numbers: "+mul); } }
        //display output on the screen

When the above code is executed, it produces the following result

The multiplication of two numbers: 308.6408

 

Multiply two floating-point numbers in C# – Entered by user

In this example, the user is asked to enter two floating-point numbers. Then the multiplication of these two floating-point numbers is calculated and displayed on the screen in C#

Program 2

// Calculate multiplication of two floating-point numbers in C# program 
using System; 
public class Mul_Of_Two_Floats { 
    public static void Main(string[] args) { 
        float n1, n2, mul; //declare variables
        Console.WriteLine("Find multiplication of two floating point numbers: "); 
        Console.Write("Input number to n1: "); 
        //Ask input from the user for n1
        n1=Convert.ToSingle(Console.ReadLine());
        //Reading the value for n1
        Console.Write("Input number to n2: ");
          //Ask input from the user for n2
        n2=Convert.ToSingle(Console.ReadLine());
            //Reading the value for n2
        mul=n1*n2; //calculate multiplication
        Console.WriteLine ("The multiplication of given two floating-point numbers: "+mul); //display result on the screen
        Console.ReadKey(); } }

When the above code is executed, it produces the following result

Find multiplication of two floating point numbers:
Input number to n1: 5.12
Input number to n2: 6.23
The multiplication of given two floating-point numbers: 31.8976

 

In the above code, the user asked to enter two floating-point numbers and the given floating-point numbers are stored in variables n1 and n2 respectively.

Then these two numbers are multiplied using the multiplication(*) operator and the result is stored in the mul variable.

Finally the display statement is used to print the multiplication of numbers

 

Multiply two floating-point numbers in C# – using function

In this example, the user is asked to enter two floating-point numbers. Then the multiplication of these two floating-point numbers is calculated and displayed on the screen using user defined function in C#

Program 3

// Write a program calculate product of two numbers using function 
using System; 
public class mul_Two_Num_Fun { //class declaration
    public static float pro_Num(float num1, float num2) { 
        float product; //declare float variable 
        product=num1*num2; //calculate multiplication of the given numbers
        return product;//return value to main method 
        } public static void Main() { //main method
            Console.Write("Enter number for n1: "); //Ask input from user 
            float n1=Convert.ToSingle(Console.ReadLine()); //Reading the input 
            Console.Write("Enter number for n2: "); //Ask input from user 
            float n2=Convert.ToSingle(Console.ReadLine()); //Reading the input 
            Console.WriteLine("The multiplication of {0} and {1} is: {2}: ",n1,n2,pro_Num(n1,n2)); } } //display result on the screen

When the above code is executed, it produces the following result

Enter number for n1: 6.4
Enter number for n2: 8.5
The multiplication of 6.4 and 8.5 is: 54.4:
