Multiply Two Floating Point Numbers in C

Float is a shortened term for "floating-point." By definition, it's a fundamental data type built into the compiler that's used to define numeric values with floating decimal points. A floating-point type variable is a variable that can hold a real number, such as 4320.0, -3.33, or 0.01226. The floating part of the name floating point refers to the fact that the decimal point can “float”; that is, it can support a variable number of digits before and after the decimal point.

Floating-point range

Sample

Input − a=11.23 b=6.7 

Output − 75.241 

Explanation − Use of Float variables. In this program, the user has two numbers (floating point numbers)means float variables. Then, the product of those two numbers is stored in a variable and displayed on the screen.

Example

#include <stdio.h>
int main() {
   float a, b, c;
   a=11.23; b=6.7;
   c = (float)(a*b);
   // Displaying result up to 3 decimal places.
   printf("%3f", c);
   return 0;
}

Output

75.241
