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, binaries
|
|
|
|
Notes:
|
|
- Under Linux x86_64, floating representation is 128-bit (quadruple
|
|
precision format). Thus precision is much better than HP28S.
|
|
|
|
========================================================================

|
Here is a list of HP28s reserved words.
