I did indeed. Hmm.... I tried -Ans( and everything to get a negative number.......... I'm really trying to avoid writing the subroutine to do it for me..... there must be an easier way....

As far as Axe is concerned, 65535=-1 ;) The obvious solution is to test if G is less than 0, and, if so, display a negative sign and then -G.

you try this? It doesn't sound to hard

I even wrote a routine that will do that (for the homescreen, but you can adapt it) as a response in the feature requests topic, but others had already posted. For reference, it would go something like this:
Lbl DSN
If r1<<0
Disp "-
End
Disp r1➤Dec
Return
Then you'd just replace "Disp X➤Dec" with "DSN(X)"
Something I'd like to reiterate: There is absolutely no difference between, say, 65535 and -1. Which way it is interpreted depends on the routine acting on it (for example, < vs <<)

I thought I remembered someone say that <<0 will only be true for 0. I guess i must be wrong :P.

More likely just misremembering. The closest statement to that that would be true is that X≤0 is only true if X is 0. :)

Thanks guys. @saintrunner Yes I did try that...... @calcdude84se Thanks so much, that drastically sizes down the subroutine I was writing.

Yeah once I get this coordinate system in, I may do a DoorsCS style Menu GUI on the bottom that comes with several geometric/algebraic functions...

EDIT: RAGE RAGE RAGE lol. It still doesn't work. fml. ACTUALLY WAIT.... atm, I will be able to add slopes and slope intercept form equations to the program because they don't require coordinates.... w00t.

Currently adding slope form and slope intercept.... I will make it so that when you press MODE, it will display a box of everything about your line... does anyone know how to use different programs and skip around between the programs like in BASIC? Oh wait, subroutine. I got it now :)

at first I thought this was some program that did real graphing like with formulas. That would be cool. This looks great too, tho.

Thanks, I was thinking I would take a new approach to graphing..... people would get a better visual if they could draw the line themselves than punching in numbers...
