In this program, you’ll learn to Multiply two Floating Point Numbers.
The product of these 2 Floating-Point Numbers which are “a” and “b” is stored in a variable and displayed on the screen.
To understand this example of Floating Point Numbers, you should have the knowledge of following C programming topics:
- Data Types
- Constants
- Variables
- Input Output
- Operator
Program to Multiply Two Numbers
#include <stdio.h>
int main()
{
double a, b, productOfNumbers;
printf("Enter the numbers: ");
scanf("%lf %lf", &a, &b);
productOfNumbers = a * b;
printf("Product = %.2lf", productofNumbers);
return 0;
}
Output
Enter the numbers: 2.4
1.12
Product = 2.69

In the above program, the user has been asked to enter two numbers.
The two numbers given by the user is stored in variable a and b respectively. This is done using the scanf()
function.
Then, the product of a
and b
is evaluated and the result is stored in the variable productOfNumbers
.
Finally, the productOfNumbers
is displayed on the screen using printf()
function.
Notice that, the result is round to second decimal place using %.2lf
conversion character.
