Function to Find sum of two floating-point numbers in C#

In this tutorial, we will discuss the concept of Function to Find sum of two floating-point numbers in C#

In this topic, we are going to learn how write a program to add two floatig-point numbers using function in C# programming language

sum of two floating-point numbers in C#

sum of two floating-point numbers

Program 1

//Write a program calculate sum of two numbers using function
using System; 
public class Sum_Two_Num_Fun { 
    public static float sum_Num(float num1, float num2) { //function definition
        float total; 
        total=num1+num2; //calculate addition of two numbers
        return total; //return value
        
    } 
    public static void Main() {
        float num1=45.8f; //declare and initialize float variable
        float num2=56.9f; 
        Console.WriteLine("The sum of {0} and {1} is: {2}: ",num1,num2,sum_Num(num1,num2)); } }//display result

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

The sum of 45.8 and 56.9 is: 102.7:

Sum of two floating-point numbers using user input

Program 2

In this program, the user asked to enter two floating-point values. these two floating point values are stored in variables n1 and n2 respectively. Then two numbers are added using + operator and the result is stored in the total variable.

// Write a program calculate sum of two numbers using function
using System; 
public class Sum_Two_Num_Fun { 
    public static float sum_Num(float num1, float num2) { 
        float total; 
        total=num1+num2; 
        return total; 
        
    } public static void Main() { 
        Console.Write("Enter number for n1: "); 
        float n1=Convert.ToSingle(Console.ReadLine()); 
        Console.Write("Enter number for n2: "); 
        float n2=Convert.ToSingle(Console.ReadLine()); 
        Console.WriteLine("The sum of {0} and {1} is: {2}: ",n1,n2,sum_Num(n1,n2)); } }

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

Enter number for n1: 34.67
Enter number for n2: 56.8
The sum of 34.67 and 56.8 is: 91.47:

In the above program, two floating point values 34.67,56.8 (get input from the user) are stored in n1 and n2. Then given two values are added using the plus(+) operator.

Then the result is stored in another variable total.

Finally, the result is displayed on the screen (Calling the function)using display statements in C#
