IF statement issue

FlybyLV 04 Dec 2020 19:53

Hey guys. Maybe someone can help me with this, I can't wrap my head around. As there is no "AND" command to use as in EXCEL. I am unable to solve an issue as I can't figure it out how it is possible to do something in TI BASIC. In excel I could figure it out but I am just stuck at reading wiki here.

What I would like to do is:
Variables X/Y.
If X and Y is positive subtract highest value from lower to have a positive answer.
If X and Y is negative subtract highest value from lower. -10-(-8)=-2
IF X is positive and Y is negative (And Vice versa) then add both together and treat both as being positive. X: -10 Y: 8 =18

Is there any way to do it?

Okay, I am overthinking this too hard.

It can be left only as this.

Disp "LAT A"
Input A
Disp "LAT B"
Input B

A-B->C
IF:C<0
Then:C*(-1)
Else:C

But honestly it doesn't work. I am doing something wrong with syntax, but it is literally as in wiki written ;/

Input "LAT A:",A
Input "LAT B:",B
A-B→C
-C(C<0)+C(C>0

Are you trying to store the output to a variable or Ans?

Also, your code doesn't work because you're missing the End command.

Trying to store to a variable. I've scraped this together seems to work. But I am not sure why initially my written code wasn't taken, I copied something similar from a different project and applied my needs to it and it works. It's a mystery to me.

If A-B<0
Then
B-A->E
Else
A-B->E

If C-D<0
Then
D-C->F
Else
C-D->F

Kinda works, but then again it doesn't. Maybe someone knows why the code stops sometimes after IF arguments and just gives the output "DONE". Values entered would be:
A - 48.9
B - 48.63333
C - 12.516666
D - 13.2
G - 48.76665
It happens IF A-B<0 is true ;/

Lbl C
Disp "LATA"
Input A
Disp "LONA"
Input C
Disp "LATB"
Input B
Disp "LONB"
Input D
Disp "Mean LAT"
Input G
If A-B<0
Then
    B-A->E
Else
    A-B->E
    If C-D<0
    Then
        D-C->F
    Else
        C-D->F
Degree
sin(G)*F->M
(F*60)*cos((A+B/2)->L
M*0.5->N

You need the End commands after an If-Then-Else statement, or it won't work.

The Starter Kit is a great place to look at for beginners.
