RPN-PRGM: New Windows console application emulating HP calculators

[Aacini]

Nigel,

Thanks a lot for share your first experience with RPN.exe program.

Did you read the (extensive) manual? I invite you to pay attention to two features unique to this application:

• The management of the IEEE-754 special values described in the user's manual, like Infinites, the NotANumber entity, negative zero, etc. This means that RPN.exe expressions will never produce an error! For example, this calculation:
  
  Code:
  

  
rpn 4 0 / 1/x
  that is equal to inverse of Infinite, gives zero as result, that is the right answer! Isn't it?
• The management of 80-bits floating point numbers, that allows to enter and display numbers with 19 decimal digits and an exponent of ten above 4000.
  

I'll appreciate it if you could give any additional comment about this application...

Antonio
