RE: RPN-PRGM: New Windows console application emulating HP calculators
I am working on a more accurate method to convert an 80-bits floating point number into a 19-digits decimal ASCII string. It will be ready in the next version of RPN.exe, besides HPSTACK mode that emulates the HP 4-registers stack management and some other minor changes.

I have to say I was very surprised and did not get reasoning that all the stack items get lost and "erased" to -1.#FLW when the stack underflows. I understand that with RPNPRGM you can use the switch but it might be useful to be able to change operation of the stack during interactive operation as well. Well, you should realize that the Overflow/Underflow condition is a state of the whole stack, not just of one register! I am pretty sure you'll appreciate the next RPN.exe version with the HPSTACK operation implemented...

It seems I copied the results of the forensic test and, after that, I slightly modified the Floating-Point to Decimal conversion method, so I forgot to run again the test and copy the new results... I fixed the results in the user's manual; this will be reflected in the new version... Antonio |
