## What is Abacus The Calculator?

Abacus Calculator is a simple to use calculator app for both iPhone and iPad.  Following the rules known in the UK as BODMAS but used all around the world for calculation ordering to produce a universally accurate result and providing you the tools to use it.

Basic functions include brackets, square and square roots and constants for Pi and Euler's number (e) and a backspace key so you don't have to remove the whole of a wrongly entered number or calculation.

The backspace key will now navigate back through the entire calculation not just the current number.
Added a section to the settings app to allow for some customisation:
   There are 4 options of display formatting (these do not affect the underlying calculation)
      Normal - Uses the existing scheme and is the default (1000)
      Decimal - Adds in commas to mark boundaries (1,000)
      Currency - Adds in the local currency symbol and 2 decimal places (£1,000.00)
      Scientific - Displays all output in 10 to the power notation (1E3)
   Added various colour options to the interface:
      Calculator Red (This is the existing scheme and the default)
      Forrest Green
      Sky Blue
      Pinks and Purples
      Sunflower Yellow
      Black and White
      White and Black
The size of the button text has been increased by 20%

Various bug fixes that prevent bad ordering of operations.

### 1.0.1 — 2017-02-07

This version has a few minor changes based on user feedback:
    * The main display and the status display have a small amount of padding on either side to move the text away from the edges.
    * The status display and text have been increased in size by 37%.
    * Text in the main display and status display will shrink when necessary to fit more in.
    * If the status display becomes full you will lose text at the beginning rather than at the end.
    * The app will also work if you hold the device upside down.
