Hi,
I copy a max version patch that should filter jittering numbers:

jittering.pd

Why it output floats? I don't want it to output float rather same numbers (integers) as input

@KMETE The average/mean of 1 and 2 is 1.5. Put an [i] after the change and it will round to the nearest integer.

Edit: actually [i] does not round, it just strips the decimal so 1.5 becomes 1. [expr round($f1)] will round.

A hidden source of trouble with this approach is that Max has integer-only operators while Pd only has floats.

In Max (IIRC), 3.1 --> [+ 2] produces 5, not 5.1. 3.1 --> [+ 2.] (with a decimal point) produces 5.1.

In Pd, the "dot" thing doesn't exist. If you're copying a Max patch that depends on integer-math behavior, you can't just copy it directly -- you need to handle the integer conversion explicitly.

I've gotten bitten by this multiple times when going the other direction (building something in Max and expecting float ops).
