Edit: Noted possible substitution to simplify

As previously mentioned on the TI59 the terms for the polar format number is the reverse of the 67, on a TI59 after the P->R and R->P conversions you end up with 30 in the x register, so to work like the t159 after you do the R->P conversion press x<->y to get 30 into x. The other thing is in your list above the P->R conversion should be f-1 not g-2, g-2 is conversion to radians.

Paul.

Thanks Paul! I ran this probably 10 times, and got alternately the 0 and the above, and could not find why. They should never have put R<>P and D<>R so close together on the keyboard, this is not the first time this got me.

So, yes, on the 67 it is indeed 0.

I suppose I should go correct the listing [Now done] since the original has been quoted and for all time will show this error . How humbling...
