Summary
Hehe, no way...
Pascal
function MakePercentage(const Step: Longint; const Max: Longint): Longint;
Parameters
| Parameters | Description |
| const Step: Longint | Sorry, no can do. |
| const Max: Longint | No idea, but I do know that passing 0 will trigger an assertion if you have assertions enabled or a runtime error (EDivByZero) if not. |
Return Value
All I have to say about this is that it is very well possible that the result may be larger than 100 and that the sign of the arguments is preserved so it is possible that the result is negative.
Description
I dare not describe this function's purpose. See the Notes section below. As a tribute to that wonderful article this function has been designated the alias HowAOneLinerCanBiteYou. You are encouraged to use that alias in your applications as opposed to the much more readable and self-explanatory name MakePercentage :-)

Notes
For a very educational dissection of this function have a look at the article written by Robert Marquardt entitled " Lessons in good programming or how a one liner can bite you" available at the Voyager section on the JEDI website.
