how to "round" numbers to decimal ?

How to make all numbers in, i.e, a range of n0 to n9, be only n ? (25 ->
20, 17 -> 10...)

Hey, great ! Thanks to both of you for these two different ways to do
it. That's supercool.
cheers

you could also use expr - for some reason %\$i1 does not work in
expr, but there must be some logic to it (probably because expr is
C-like expression in which modulo is done in a totally different
way....)

correct, use the function rather than the operator. i think it's in the
expr help/ref somewhere but i don't have it in front of me (i'm not a C
programmer, just an expr user). from memory, i think it's
mod(\$i1,10)

I use this method Mattijs suggests all the time, but with a secondary input hooked up, for variable quantization of the signal. This is by far the most useful little abstraction in my arsenal.

actually it was
(\$i1 %10)
which gives
OR

Or you could do:
expr (\$i1/10)*10
Since everything is expressed in int math, you'll only get 10's.
Below is an abstraction that will round to arbitrary decimals/tens,
etc. and also handles negative numbers.

maxobjects.com lists f0.round, running on Classic Mac OS, OS X, Pd,
and Windows. There may be others (the word "round" matches a lot of
items). In case you wanted an external.
