100 TI-BASIC Optimizing Tips
« on: December 14, 2011, 12:52:57 pm »
I think we need this thread at some point :)

I'll post some first! :D

1. 2(X-1)→X to 2(X-1→X to 2X-2→X if numbers are small enough.

2. X*100→X to XE2→X

3. (X-3)/5→X to 5-1(X-3→X

4. If X=1:0→X:Goto A:If X=0:1→X:Goto A (I see this a lot) to abs(X-1→X:Goto A to not(X→X:Goto A

5. Disp "A":Disp X:Disp "B" to Disp "A",X,"B

1. Disp X   to X  (only as the last command in a program, and messes up Ans)
2. seq(2^X,X,1,8 to 2^cumSum(binomcdf(7,0

I think you forgot an Else before the second If there.

X/100 to sub(X is a very useful one.

I see many people using this getKey routine:
0→K
While K=0
getKey→K
End

It could be optimized to this:
Repeat K:getKey→K:End

EDIT: Here's jacobly's way if you're interested:
0:Repeat Ans:getKey:End

You can take out the 0 and just use Repeat Ans:getKey:End because getKey returns 0 if no key was pressed.

Might as well do .1X since sub() is a 2 byte token :P

That divides by ten, not 100.
