I am trying to create and or fix this program I found online to give me simplest radical form output but my TI 84 plus se gives me errors.
Is something wrong with the code?
Code: :1→A
:2→I
:While I{^2}≤abs(R
:While not(fPart(R/I{^2}
:R/I{^2}→R
:AI→A
:End
:I+1+(I>2→I
:End
:ClrHome
:1+int(log(A
:If A≠1
:Output(1,1,A
:Ans-(A=1
:If R<0
:Then
:Output(1,1+Ans,"{i}
:Ans+1
:End
:If 1≠abs(R
:Then
:Output(1,1+Ans,"sqrt(
:Output(1,3+Ans,R((R>0)-(R<0
:End
Can I correctly assume you copy-pasted that from SourceCoder (Cemetech's TI-BASIC editor)? If not, be aware that {^2} is the squared key, the one above [LOG] on your calculator keypad. Similarly, {i} is the imaginary number i, aka [2nd][.]. What line does the error occur on?
Yes, you're correct. I'm aware of that. I just solved the problem by reviewing the code, I was missing an entry at the beginning which stated ( :Prompt R), I'm now able to get answers in radical form. Thank you for your help.

No problem. Do make sure that you understand how this program works, of course. That's a key part of learning any new language by playing with existing code, including TI-BASIC. And don't hesitate to ask if there's anything in the program that doesn't make sense to you.
