RE: algebraic to RPN/RPL online converter
(1+(1+I)^N)/I converts to RPN just fine:
Code: @ RPN of (1+(1+I)^N)/I However, with the Evaluate gives an answer of 1+2/I . I have not assigned any values to any variables.

RE: algebraic to RPN/RPL online converter
1. The SQRT function does not copy to the Expression box. Thankfully the square root symbol does.
2. RE and IM are not allowed in the converter. Do you plan to implement complex number functions? Currently a value of i that is assigned to a variable has a value of 1. 3. Do you plan to have an option to use the LASTx feature? Same for SWAP or ROLL (down)? Or least to turn those functions on? Promising converter! Eddie

RE: calculator and algebraic to RPN/RPL online converter
Hi Eddie,
Today, I've seen this thread and your comment. Could you please tell me if you find resolved the some problems you mentioned, e.g., SQRT, RE and IM function? I wonder how could an algebraic expression like, say (2+x^2+y), contain 'LAST' feature or any other stack function as SWAP or ROLL. Perhaps, this should not be an algebra to RPN task. Xavier
