WP 34S mini-challenge

I am somewhat intrigued by Gerson's solution here (and I'm sure he has one). It seems like it would be an improvement on those submitted thus far even though it isn't exact -- it deals with the two different stack sizes, doesn't require an integer mode switch and doesn't take forever to execute.

Time will tell of course.


The divide by two is what is stumping me. x² RCL+L 2 ÷ is the obvious solution but it doesn't preserve the stack and saving the stack consumes more steps than are available. I can't think of a way to circumvent these issues besides saving T and using COMB. Even using the statistical Σ+ command doesn't seem to help.

Integer mode can replace the 2 ÷ by SR 01 or ASR 01 without impacting the stack usage but that is specific to integer mode. We didn't support implicit integer to real conversion for all non-real defined functions (rightfully so BTW). Likewise my proposal to include arithmetic operators with a small constant argument was vetoed, otherwise the space & stack saving ÷2 instruction would have been available.

I think I'm missing something here.....
