TI-83+ Basic- Decimal/Binary converter
#1
Okay, I'm taking a digital Circuits course, so I figured I'd cook up a TI-BASIC converter, since the function wasn't already built in.

If only it were that easy.

This is what I have so far for the dec to bin part:
Code:
Lbl B
Disp "DECIMAL:"
Input D
For(X,8,0,-1)
If (D-(2^X))>0
Then
O+(10^X)->O    'That's a Store In command, not a minus and a greater than.
D-2^X->D
End                    'For the IF
End                    'For the For loop

My problem is that a decimal 1 comes out as 0, and a decimal 255 comes out as 11111110. So does 256.

What am I doing wrong? Or is this just not possible?

0->O
For(X,8,0,-1)
   If (D-(2^X))>=0    '#### <- you forgot the equal sign here
   Then
      O+(10^X)->O
      D-2^X->D
   End                
End
