Best calculator available anywhere! Wish there was an iPhone version. If its not on the canned functions, write your own.
If you don't use it you are probably missing out..
It is the preferred calculator on anyone's computer. Once you have agreed to rethink calculator use to accept RPN you will not be happy with any other calculator. I learnt RPN on HP handheld machines, and now use Excalibur on every machine I use.
The different categories of function.
The programming language is a bit close to assembler for programmers who do not use assembler.More

haven't found ANY issues with it in years of use.
For day-to-day calculations, this app should meet your every need. As developer Dave B notes in his help file, there may be some precision issues that cannot be easily remedied due to floating point representation on the PC, but any user worried about precision at 1E-08 would & ought to be using some other app.
RPN (it rules, y'know!)
scientific, programmer and conversion functions
- Would like improved indications -- cues or clues in the GUI graphic or in mouse-over pop-ups -- to speed key association with row+column in the 10x4 function button array.
- would like to be able to change/select a function bank w/o resorting to the mouse to do so.More
Using the Excalibur .
I am a mechanical engineer and have been using Hewlett Packard programmable calculators over for over 40 years and as a result am an ardent supporter of the RPN system.
A associate of mine introduced me to Excalibur some 10 years ago.
I have been using this software exclusively as it is more convenient and provides all the features found on my HP calculator.
Convenient PC based More
Excellent free utility. As a mathematician--an algebraist to be specific--I find RPN practically and philosophically superior to (and more algebraic in nature than) so-called algebraic notation. I've used excalibur for many years. It is one of the first additions when I upgrade my computer. More
