Multiplication of two floating point numbers in C

In this tutorial, we will discuss the concept of Multiplication of two floating point numbers in C

In this topic, we are going to learn how to multiply two floating-point numbers using the multiplication operator in C language

What is multiplication

The multiplication is a method of combining a group of equal size. The multiplication is an arithmetic operation inverse of division

It is one of the four basic operation of arithmetic calculation others being addition,subtraction,division

The product of two numbers means, it is the operation one number is combining within another using multiply(*) operator.

The answer of a multiplication operation is called as “product”

Find product of two floating point numbers in C

Program to product of two floating point numbers

The program calculates the product of the given floating-point numbers using “*” operator

Program 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    double num1=2.2,num2=5.0,product;
//Declare and initialize double variables
    product=num1*num2;
//Calculate the product
    printf("product of %.1f and %.1f is=%.2lf",num1,num2,product);
//Display the result on the screen
getch();
    return 0;
}

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

product of 2.2 and 5.9 is=11.00

Program to product of two floating point numbers – Takes input from user

The program allows the user to enter two floating-point numbers and then it calculates the product of the given numbers using multiplication operator

Program 2

#include <stdio.h>
#include <stdlib.h>

int main()
{
    double num1,num2,product;
//Declare double variables
    printf("Enter two float numbers: ");
//ask input from the user
    scanf("%lf %lf",&num1,&num2);
//store the input in the variables num1,num2 
    product=num1*num2;
//Calculate the product
    printf("product of %.1f and %.1f is=%.2lf",num1,num2,product);
//Display the result on the screen
    getch();
    return 0;
}

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

Enter two float numbers:3.5
5.5
product of  3.5 and 5.5 is=19.25
