Hi,

i was wondering if there is an object that can compare the signs of integers. i mean if two integers have the same sign or not. I know its not that difficult to do it combining logical comparison objects but i want to avoid mess as much as i can.

thanks

Multiply them. If the result is positive the signs were the same, if negative they were different.

It doesn't work if the one number is 0

True. Zero complicates things. Yet the problem is really one of definition. What sign did you want zero to be?

I remember Claude pointing out something recently I had forgotten from hardware lectures, that depending on the microprocessor and compiler you can end up with +0 or -0

However Pure Data treats this, you would be wise to wrap up a little abstraction of your own that deals with it explicity via [sel 0]

At least then you are in control.

a.

Thank you obiwannabe!
