The black screen with the three hexagons are not a welcome feature. This was not a good change I often need to see the current calculator and results while typing in other apps.
#RPN SCIENTIFIC UPDATE#
My only complaint, and costing one star in my rating, is the 18-May-22 update - which now blanks the screen when the app is „in the background“. (The 15C is an enhanced 11C having owned one, it‘s worth it to purchase) For casual users, these two calculators might be all that are ever needed. I really like the „hot key“ option for three paid-for calculators.īasic app comes with „free“ (with ads) versions of the 11C and 12C. Myself, I purchased the big three: 16C, 15C, and 12C (not the platinum version). Try going to Settings and touching the button 'Restore purchases', reinstalling the app, or restarting the phone to force the app to get the purchases.Ģ0-May-22 - good to great, only one complaintĪ collection of what many people consider the best calculators ever made, let alone by Hewlett Packard. Sometimes the App Store takes a while to send the receipts of purchases to a new installation, it has been happening more frequently in the last few weeks, Internet congestion I guess. I even tried purchasing again direct from iPhone but Apple doesn’t allow and says it was already purchased, so at least Apple is protected the user. Reset purchases from the Settings screen does nothing. I’ve tried multiple times deleting and redownloading and rebooting phone. When using on my iPhone, which is more typical, I still have the ads! And you can’t pay for it again on the phone because Apple figures the app was already paid for. It claims to have family sharing, so I paid using my iPad. In fact, to the point that I went ahead and paid to get rid of the ads. Unfortunately, no recent updates have been made.The calculator app itself works well enough. All in all, this app should please all users who require a full-featured RPN calculator. We have not come across any problems in our tests, since Excalibur did not freeze, crash or pop up error dialogs.
It has a good response time and includes a help file.
#RPN SCIENTIFIC SOFTWARE#
The software program runs on a very low amount of CPU and system memory, so it is not a concern to the computer's resources. angle mode, numpad lock, comma format, footprint size, tax constant). On top of that, you can copy the entire stack, view system usage statistics and define a custom set of functions, as well as configure program settings (e.g. sine, cosine, tangent), fractions and logarithms. For instance, when it comes to scientific functions, you can use trigonometric tools (e.g. So, it is possible to list functions according to their bank. The interface of the program is based on a standard window with a familiar layout. Moreover, you can carry Excalibur with you whenever you're on the move. More importantly, no leftover items can be found in the Windows Registry or on the hard drive after program removal.
In other words, you can save the tool on a removable device (like a USB flash drive) and directly run its executable file on any computer.
#RPN SCIENTIFIC PORTABLE#
This is a portable app, so Excalibur does not come with a setup pack. It can be used by students, for instance. Excalibur is a RPN calculator (Reverse Polish Notation) designed for users who work in specialized domains, such as Computer Science, Physics or Statistics.
