What is the value of sgn(NaN) or sgn(nan)

OK. Understand. That makes sense. You definitely need a copy of that array on each machine for zero communication overhead.

I have to get some more experience with multi-locale stuff. I normally only get access to the slowest multi-core machine we have. My team tell me they need the cluster to do their consulting tasks and tell me to stay away from the their!! cluster

I notice that signbit() has changed type in 2.0. Not terribly useful but there it is.

Your rewriting the definition of a floating point number is only going to confuse you.

Hi @damianmoz —

I'm not seeing the 2.0 type change to signbit() that you're referring to. It looks like it returns a bool as it has for as far back as I could find documentation on the routine:

What am I missing?

Silly me. I apologize if my incorrect assumption has confused anybody in any of my past discussions

i have used my own version in the past which now uses transmute and that has always been an int(w) to reflect how I have long used the concept.

Again, sorry for any confusion I have created.
