How to Get a Float Result from Integer Division in C ?

Casting Integers to Floats for Accurate Division

In C , dividing two integers, such as in a/b, results in an integer quotient. To obtain a float result, one must specifically cast the operands to floats.

Problem Statement:

When using integer operands in a division operation, the result is truncated to an integer. How can one prevent this and maintain the integrity of the numbers?

Solution:

To remedy this issue and ensure a float result, cast the operands to floats:

float ans = (float)a / (float)b;

By explicitly converting the operands to floats, the division operation will produce a float result, preserving any decimal precision.

Example:

Consider the following code:

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
  int a = 10, b = 3;
  float ans = (float)a / (float)b;
  cout << fixed << setprecision(3);
  cout << (a/b) << endl;
  cout << ans << endl;
  return 0;
}

Output:

3
3.333

As seen above, the casting ensures a float result, retaining the correct decimal precision.
