Any Reason This Shouldn't Work?
« on: October 06, 2010, 04:59:28 am »
Ok, so I started working on my own version of a calendar generator, just for the fun of it. But when I get to my display routine something happens and I can't figure out why it's happening :( It really is not making any sense to me and I can't explain this.

The code section is this:

Code: [Select]
Text(H,12F-9,E
H=14
F=4
E=1

It just doesn't make sense to me because Text(H,39,E and other things without a variable in the second argument work fine. Anyone know?

It works for me, weird. Maybe it's a bug in your version of the OS? I'm using a TI-83 Plus OS 1.19, btw.

That's what I figured, that it should work. Ugh. This is bugging me now. This has never happened before :(

Are you sure that the variables are those numbers?  Try putting an iPart() around the variables?

Ah, maybe they somehow got saved as complex numbers? Just an idea.

Either way, what is the problem?  Like that is the error?

Well each time I get the domain error I always check what U (well now it is U instead of F) and it returns four. But I did put the iPart( around it and it seems to have fixed it ???

If you're calculating F inside a program, vars often have 0.00000000000001 or something inaccuracy, especially when it's calculated after a bunch of operations. It's horrible to debug x.x I've actually given up several projects before before I found that bug. Stupid TI-OS :(

Well I use round(#,0 in it but that should just return the integer part of a number, without any decimal places.

It didn't work after round(#,0? O.o That's weird.

No, it all works. I'm just saying that if you're right about it tacking on a negligible decimal point that is the only place I could see it coming from.

Yeah, and the homescreen automatically rounds so that you always are looking at these horrible numbers like 23.000000000008 all the time

Press [Math] [0] (hold [up] after this if need be) and make the equation the vars you want (H, F, and E).  Press [enter] then [down].  Enjoy learning about the variables in their entirety! ;D

Wait, what is that supposed to do exactly?

Also, is iPart( the only solution to this? I thought round( would solve it all but I guess not :(
