Sorry mate, I thought you were after some surveying stuff.
Still, read above. Dealing with single numbers on the stack rather than vectors or matrices is a thing of the past. So, I congratulate HP48 development team for not making polar-to-rectangular routines part of the userRPL system.

Not much call for programs where i work, everything is calculated using CAD software & uploaded into Leica Total Stations (jiggers) via memory cards, however we just got a loan of the latest Leica model TS16 & it takes SD cards (haven't tried a HP50 SD card yet)
The age of programming may be returning.

A GOOD REASON TO STAY AWAY FROM SYSEVALS (unless you really need to)

You are correct, the SYSEVALs do not return the correct answer if the inputs are exact integers. Type checking is indeed necessary for general use but the SYSEVALs are significantly faster inside a loop.

Also, while I agree that P->R and R->P are not strictly necessary in RPL, the lack of these functions may be disconcerting to users unfamiliar with RPL, and it may not be obvious how to replace them.
