I found how to turn decimal to root from this thread that I can't post cause I'm new:
Input "DECIMAL: ",R
round(R²,0→R
R→A
Repeat 0=fPart(R/A²
A-1→A
End
ClrHome
Output(1,1,A
Output(1,3,"√(
Output(1,5,R/A²
Here's is what the user wrote in this:
"If you want to make it work for any order of root (cube root, 4th root etc.) you can replace ^2 with ^I, where I is the index prompted for I at the beginning."
In which it showed how to write a program that it does.
Issue lies when I try to use anything that isn't square root. The answers for square root is flawless but trying to use cube root or 4th root, it doesn't show the right answers. How will I go on to fix that so the custom index works?
