Excalibur for Windows

Outstanding!. Best calculator available anywhere! Wish there was an iPhone version. If its not on the canned functions, write your own. Pros: RPN Cons: iPhone version

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. Pros: RPNThe different categories of function Cons: The programming language is a bit close to assembler for programmers who do not use assembler.

must have for hp calc users. excellent for those doing work on the computer and natually want their caclculator there not buried. I have it set to hot key Alt-ctl-C and with just a keystroke can get my calculator in my face. Pros: excellent. functional. handy Cons: need ipad app. need mouseover of functions showing the hotkey.need programmable hotkeys, I like 1/x and the clear stack is next to exchange key

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. Pros: RPN (it rules, y'know!)8-element stackscientific, programmer and conversion functionsfraction entry Cons: Trivial improvements: - 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.

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. Pros: Convenient PC based

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.
