Version 6.5

Hi all,

I just released the latest update which adds split-screen support to Android Nougat (or higher) devices. Sorry for the delay on this feature but the built-in support for selecting layouts (and font-sizes) works well for some parameters but not for aspect-ratio.

Anyhow, there are three keyboards (portrait, landscape and square). Square was previously only for tablets but split-screen changes that. The system will automatically pick the best keyboard and screen height for the size it is given and every device is a bit different. I did my best to unify the three keyboards while changing as little as possible.

A few side effects of adding split-screen is that now the free version gets landscape support. The two features are not mutually exclusive. Also, all orientations now get a scrolling display and all orientations for the programmer-mode will now get the binary-bit display.

Version 6.4

Hi all,

I just released Version 6.4 which lets you choose one of two Algebraic Modes (Prefix & Postfix). Prefix allows you to enter calculations as you would read them, while postfix allows you to enter numbers first, then the operations.

This way, everyone gets what they want :)

Version 6.3

Hi all,

I just released an update that’s been requested by many, many folks. Algebraic Calculations in Expression View are now entered just like you would read them. Here’s the full change list:

  • Algebraic mode now more closely matches textbook-style entry. Calculation expressions can be entered as you would read them. You can now enter 3sin(45) as you see it.
  • Complex i and all constants (like π) are now treated as variables. You can now enter as you see it. This also works in RPN mode.
  • Operator precedence has been lowered for functions MOD, NCR, NPR and Δ%. This more closely matches industry-standard computational engines (example on Wolfram Alpha). They now sit just below the S in PEMDAS.

Google Play BETA

Hi all,

I’ve added the opt-in links to the Google Play BETA. Feel free to participate, or not. The choice is yours but, whenever there are updates, I always release them to the BETA users first.

You’ll need to own the respective application and then sign-in with the Google account you downloaded/purchased it with.

Also, once you become a BETA tester, you can’t seem to write a review anymore.  The system only lets you leave private feedback at that point, so don’t forget to leave a 5-star review before joining. =)

Version 6.2

I just released the latest BETA version to all users. This version adds the following:

  • The MOD function now supports complex numbers.
  • I’ve improved a lot of subtle expression logic.
  • I’ve updated some text on a few of the shifted buttons.

Additionally, all MOD operations in the Scientific Mode have been switched over from Truncated Modulo to Floored Modulo.  In Programmer Mode, MOD will remain as Truncated Modulo because it is far more ubiquitous across programming languages.

Truncated Modulo : a mod b = a-b*trunc(a/b)
  Floored Modulo : a mod b = a-b*floor(a/b)

Feel free to google the applicable differences, but for real numbers the changes will only affect negative values.  Floored Modulo is more popular in handheld scientific calculators and gives you more options as a user anyway…so it was a no brainer for me.
