How to Get a Float Result When Dividing Integers in C  ?

Precision Loss in Integer Division: Achieving a Float Result

In situations where integers are divided and a floating-point result is desired, C may truncate the output, causing data loss. To address this issue, it is crucial to understand the principle of integer division in C and implement a method to force a floating-point operation.

When dividing two integers, C performs an integer division, menghasilkan a whole number result. This behavior persists even when assigning the result to a float variable. To obtain a floating-point result, it is essential to cast the operands to float before performing the division.

The solution involves modifying the code as follows:

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

By casting both operands to float, we ensure that the division operation is performed as a floating-point operation, resulting in a float result. The computed answer is then stored in the variable ans.

The modified code snippet is shown below:

#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;  // Integer division
  cout << ans << endl;      // Float division
  return 0;
}
Copy after login

With this modification, the output will now correctly display the float result when using ans.

By understanding the behavior of integer division and implementing the casting solution, programmers can effectively achieve floating-point results in such situations, ensuring accurate calculations and desired output values.
