# CS.FRACTION.LOSS

Possible loss of fraction when dividing integral values and assigning result to a floating point entity.

## Vulnerability and risk

When two integral values are divided, the result is also truncated to an integral value (with loss of fraction portion). When the result is assigned to a floating point variable, the intent is most probably to get a real number without fraction loss.

## Example 1

1 class Foo { 2 float Devider(long a, int b) { 3 decimal d; 4 float f = a / b; // defect 5 d = a / b; // defect 6 f = b % 2; // defect 7 f = a / f; // OK - one operand is not integral 8 return f; 9 } 10 }
