And works for me

%W1and%W2=%W3

Edit: and on a gut feeling I just typed in modulus and it worked!

I need to add some examples to the manual now that we have figured out how to use them

Did you get modulus to work?

I'll try it couple of days later (now is holidays in Russia).

P.S. You mean my expression will be: "modulus(%IW11-%IW10)<=10"?

P.P.S. Happy New Year!

What worked for me was:

3modulus2>2
%W1modulus%W2>%W3

Although I'm not sure of the output it passed the syntax check.

Edit: I'm pretty sure the above is incorrect... I got the expected results from the following

(2+3)&(3+2)=5
10%3=1

Hmmm..

Looks like Google Translate play a joke with me..

In Russian word modul' means:

|3|=3
|-3|=3

But GT translate it like "modulus"...

And "mod" is dividing operation 3mod2=1

So, I just need to know a difference between two variables without sign.
Maybe I just need ABS??? :ohmy:

P.S. If so, sorry my stupidness..

Yes modulus is the remainder of a division. 10/3 has a remainder of 1 so the modulus is 1

I have managed to get the absolute to work with the following syntax.

ASSIGNMENT
%W2=-1

COMPARISON
ABS(%W2)=1
