I realize this is a dumb question but I just can't come
up with an equation that will do this and I don't see an
internal PHP function (for version 4.3) that will do this...
Basically I need to come up with an equation/algorithm
that will round any number up/down to the nearest X.
I tried using

y +/- (y mod x)

but after I started putting in some test numbers, it didn't
always work. For example,

37678 + ( 37678 % 500 )

did not round up to the nearest 500.

Any ideas?

thnx,
Chris
