Ok so it did need to be an expression. Thank you very much!

So to get a better understanding of what's going on, am I interpreting this correctly?

jit.expr is using the round op to round to the nearest integer, so the expression is as follows:

round to nearest int((by the one divided by value set at inlet 1) * matrix float from inlet 0) * value set at inlet 1)

so if I just neeeded to round to the nearest .25 and not need the 2nd inlet, the expr could go as: round((1/.25)*in[0])*.25

Is that right? It seems so...
I figured it wouldn't need to be an advanced expression, but I need to increase my math skills.

I'll post my patch when I finish it (M4L device)
This will be very helpful in another context later on, as well:)

Thanks again:)
