Use "\" instead of "/" when performing divisions between Integers. The "/" operator returns a Single value, therefore the seemingly efficient line Click here to copy the following block C% = A% / B% actually requires three implicit conversions, two for converting the operands from Integer to Single (to prepare them for the division) and one to convert the result from Single to Integer (to complete the assignment). If you use the "\" operator you don't incur in this overhead, and the division itself is faster. While we are on this topic, keep in mind that the "/" operator returns a Double value if at least one of its operands is a Double; therefore if you wish the highest precision when dividing two Integer or Single values, you should manually coerce one of them into Double type: Click here to copy the following block ' this prints 0.3333333 Print 1 / 3 ' this prints 0,333333333333333 Print 1 / 3#
