FlowCE 2.2

FlowCE 2.2: themes you can tell apart on the calculator. Sand, Mint, Rose, Arctic, Ember, Grape
and Forest have stronger colors: cream, mint, blush, blue slate, brown, plum and green. Their old
shades were so close that the calculator's screen showed several of them alike. The new ones were
picked on a TI-84 Plus CE. Text is as readable as before, and Paper and Night are unchanged.
Everything else is 2.1: the same answers, the same speed. FlowCE Python 1.9.1 is unchanged.

Install from the website and pick a version.

Why they looked alike

The calculator's screen shows 32 levels of red, green and blue, and the old backgrounds were 1 to
3 levels apart (Ember and Grape differed by one level of blue), on a panel that squashes shades
near white and black. Now each background is at least 4 levels from every other light or dark one.

Checks

• The app is 2.1's byte for byte except the seven themes' colors and the version.
• On an emulated TI-84 Plus CE: the 898 regression problems give the same answers as 2.1 (none
  hung), interrupting with on, out of memory (8/8), 101 screen checks, 29 ways through the
  menus, and the 71 applications problems.
• Both files use the updated installer the website switched to on October 21.

Known limits

• Grape's purple stays subtle on the calculator's screen.
• One area problem with acos and asin takes over two minutes on the calculator (on stops it).
• Not every problem has steps; when no textbook method explains it, FlowCE says so.

Please report problems with what you typed
and your calculator's OS.
