C Program to Multiply two Floating Point Numbers

Posted by Annie Sanjana

This post shows how to multiply two floating-point numbers using the C programming language. So let’s go through the program.

C Program to Multiply two Floating-Point Numbers

#include<stdio.h>
int main()
{
    float var1, var2, result;
    //GETS THE FIRST VALUE FROM THE USER
    printf("ENTER VAR1:");
    scanf("%f",&var1);
    //GETS THE SECOND VALUE FROM THE USER
    printf("ENTER VAR2:");
    scanf("%f",&var2);
    //MULTIPLY VAR1 AND VAR2 
    result=var1*var2;
    //DISPLAY THE RESULT UPTO 2 DECIMAL PLACES
    printf("RESULT OF TWO VAR1 AND VAR2 is:%.2f",result);
    return 0;
}

Output

Explanation

So this C program deals with the multiplication of two floating-point numbers, in which the user enters the values. These values are stored in the variables var1 and var2, respectively.

  printf("ENTER VAR1:");
  scanf("%f",&var1);
  printf("ENTER VAR2:");
  scanf("%f",&var2);

Then the values in var1 and var2 is multipled and the product is stored in the variable named result.

    //MULTIPLY VAR1 AND VAR2 
    result=var1*var2;
	printf("RESULT OF TWO VAR1 AND VAR2 is:%.2f",result);

We are using %.2lf while displaying the result. This means that the value will be rounded off to only two decimal places.
