PEMDAS Changelog
What's new in PEMDAS 3.1
Nov 1, 2016- Updated the interface to be lighter and match the iOS version of PEMDAS.
- Updated the equation text field to a standard OS X text field (making it easier to copy/paste and use international keyboards/unicode characters with).
New in PEMDAS 3.0 (Oct 25, 2013)
- Better Mini Mode
- A Better Foundation
- Retina Display Support
New in PEMDAS 1.2 (Dec 14, 2009)
- Float/scientific/engineering formats now switch in realtime
- Formula box now scrolls, either with the arrow buttons on the keyboard or in the widget's formula bar.
- Negative exponents, like 2e-9, are now supported
- Fixed a bug that caused negative numbers in scientific and engineering to be displayed improperly (still the correct number, just didn't look pretty)
- Fixed a bug where back to back to back exponents, like 2^2^2, wouldn't work
- Info and + buttons fade out when the widget is expanded/contracted
- Subtracting negative numbers now works properly; previously 3 - 2 would give you 1, not 5.
