Result is not floating-point

The result of the division is truncated to an integer (a whole number), which is usually a loss of precision in a calculation. When dividing two values of integer types, integer division is used, which ignores any remainder. When such a result is used in a context expecting a floating-point number, it is likely that floating-point division was intended.
