I'm trying to find a way to work with a negative number, I have a y=mx+b formula that I need to use. It's a negative slope, ie y=-.85x+120 Any thoughts?

You have to convert everything to Real numbers

I don't think 05 supports REAL

"Back in the day " most PLCs wouldn't support anything but positive integers. We ended up essentially programming many routines twice. We would test the variables to see which was greater, set a bit to indicate the number is negative, then adjust the math accordingly.

That's the way I probably would right the routine if it was as simple as above.
