The way to simulate the ceiling function, if you are not using a TI-92, is 
the following:

-int(-x)

which is equal to ceiling(x). It requires no IF statements, just that 
simple formula. I discovered that by typing ceiling(x) into the TI-92, and 
it's symbolic evaluator returned -int(-x).

Note to TI-92 users: It actually returned -floor(-x), but floor() is 
identical to int() according to the manual.
