rpn28s Project Overview
========================================================================
This project plans to create a clone of HP-28S calculator language,
including at least stack, store, branch, test, trig and logs commands.
Following objects are managed: scalars, symbols
Notes:
- Under Linux x86_64, floating representation is 128-bit (quadruple
precision format). Thus precision (49 digits) is much better than
HP28S.
========================================================================
Here is a list of HP28s reserved words.
Some new commands are added. They are tagged with (+).
Already implemented commands are tagged with (*).
GENERAL OPERATIONS
+(*), -(*), neg(*), *(*), /(*), inv(*)(+), %(*), %CH(*), ^(*),
sqrt(*)(+), sq(*)(+)
