How to Avoid Integer Truncation in C Float Division?

How to Produce a Float Result from Integer Division

In C , integer division truncates the result, even when the output is assigned to a float variable. To prevent this truncation, the operands must be explicitly cast to floats:

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

In this code:

• a and b are integers, and ans is a float.
• The expression (a / b) performs integer division, and the result is truncated to an integer (3).
• The cast (float)a converts a to a float (10.0).
• The cast (float)b converts b to a float (3.0).
• The expression ((float)a / (float)b) performs floating-point division, producing a float result (3.000).
• This result is then assigned to ans.

By casting the operands to floats, the output of the division is retained as a float, resulting in the desired precision:
