Is there any way to drop the numbers after a decimal? For example if I have 2.9 I want to drop the .9 and get an answer of 2. So far I have only been able to find how to round up, but I need to be able to round down.
Thanks very much,

Michael

Round to negative is floor() and round to 0 is fix().

help floor

But if you already are using ceil() to round up, I'm not sure why you wouldn't know about floor() as well

Try the floor function.
