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
