How to Get a Floating-Point Result from Integer Division in C ?

Dividing Integers for a Floating-Point Result

Despite the use of a float variable to store the result, integer division can result in a truncated output. To overcome this issue while maintaining the input variables as integers, consider the following solution:

Cast the operands to floats explicitly:

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

This casting operation forces the compiler to perform floating-point division, ensuring a floating-point result even when the operands are integers. The example below demonstrates the expected behavior:

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

int main()
{
  int a = 10, b = 3;
  float ans = (float)a / (float)b;  // Explicit casting to floats
  cout << fixed << setprecision(3);
  cout << ans << endl;  // Floating-point result
  return 0;
}
