Interval RPN Calculator

ver 2.0.4 -- 16sep22 * Now use GNU Ada exclusively. * Elliminated use of defunct AdaCore compiler.

ver 2.0.3 -- 8jan22 * Improved coding, interface & help screen. * Reduced clutter in root directory.

ver 2.0.2 -- 12oct20 * Improved output format; added (h)-key. * Improved handling of erroneous inputs.

ver 2.0.1 -- 9oct20 * Improved coding of ifjail.cpp for better accuracy. * Improved number entry in irpn.adb for proper accuracy.

ver 2.0.0 -- 7oct20 * Converted to using Boost-Interval library. (Boost NOT needed to run). * Now works for Windows, OSX, & most distros of linux.

Brief Description

This terminal app runs on PCs or laptops running Windows, OSX or GNU/Linux. It attempts to mimic the functionality of an HP ReversePolishNotation [RPN] calculator with the added enhancement of interval output. So along with your answer, you get a good idea of its trustworthiness.

Featuring

* no installation
* no dependencies
* simply unzip in your Downloads directory, and run;
* or unzip onto a USB flash drive [w/same file format] and run.

Details

Here is the header that appears on invocation:

Operation

Type numbers and hit (enter) to push each of them onto the RPN stack. Then a single key defines the desired operation.

RPN means that you enter the numbers first, then define the operation. A unary operator, like sin, will apply the function to the number at the top of the numeric stack, then push the result back on the stack top. A binary operator will pop two values off the stack, then perform the operation on them, and push the result back on the stack top.

For those familiar with the HP RPN calculators, the number entry here differs slightly. To enter scientific notation you simply type the number as you would normally, eg "1.3e5" or "1.3e-6" followed by the (enter)-key.

In order that math OPs only require a single keystroke a unary minus is not allowed The (n)-key will negate the value at the stack top. (i.e.: typing "-1.3e-6" is not allowed)

The allowed binary operators are {plus,minus,times,divide,pow}. These are invoked with the usual keyboard keys.

The (h)-key [Help] will always show the menu.

Memory Function (mk/Mk, k=1..9):

Enter a number, then type m3 + (enter), to store it in memory #3 location. This will pop it off the stack.

Recall it by typing M3 + (enter); this puts it on top of stack, while retaining it in memory location #3.

Enhancements to user-friendliness will be coming soon!

Example output [ ln(1.3e-6) ]:

1.3e-6

1.300_000_000_000_000_000E-06 HI

1.299_999_999_999_999_840E-06 LO [ stack.top: 1 ]

-13.553_146_293_496_780_800 HI

-13.553_146_293_496_785_600 LO [ stack.top: 1 ]

Mini Thin Binding to Boost Intervals

Ada developers note that this app includes a minimal Ada-binding to the Boost Interval C++ library. But, more importantly, it demonstrates the methodology so you can expand the binding to include access to other functionality, as needed.

Setup & Running:

The application's root directory [~/intRpn/] contains files for deployment on 3 platforms: 1)OS-X, 2)linux, 3)Windows, in addition to all the source code. This app is completely self contained and will run without installing any third party software onto your system.

Unzip the archive.

Open a commandline terminal, and cd to the install directory.

Linux users should type "irpn_gnu". (runs on most linux distros.)

Mac users type "irpn_osx".

Windows users type "irpn.exe".

The h-key (Help/Hint) will show the menu. In order that math OPs only require a single keystroke a unary minus is not allowed Use the n-key to CHS (negate the stack top).

Rebuild Instructions

This app should run as delivered, but the tools to rebuild are included.

Windows => wcmp.bat

MacOSX => ocmp.sh

GNU/Linux => lcmp.sh

Thusly, modifying the main app, irpn.adb, and rebuilding, only requires an Ada compiler.

There are also interface libraries that should not need rebuilding, but if you do, you must first install Boost. The directory ~/intRpn/adabinding/ contains scripts to rebuild the interface libraries: libifgaol.a (win32), libifgaol.so (linux), libifgaol.dylib (osx). On OSX, the resulting dylib needs to be subsequently modified with the script "fixlib.sh", to make it findable.
