What's new in version 1.8.6

  • Now computes negative binary and negative octal numbers.
  • Now allows you to see the calculator interface at various scaling factors 1x, 1.2x, 1.5x, 1.8x, 2x, 2.5x and 3x. See iota-calc preferences to change the scaling factor.
  • Adds a "Restore Factory Defaults" button which restores each preference to its default state.
  • Tab key now cycles as follows: moves the cursor to just before next comma, and then just after it (great for adding parameters to a function), after the final comma the next tab press takes the cursor to the end of the expression, another tab press then moves the cursor to the results field (evaluating the expression first). Pressing tab in the results field places the cursor at the beginning of the expressions field.
  • Shift Tab works opposite of the tab key
  • Command-A now selects all of the input or output fields (depending on which the cursor currently is in).
  • Pasting when the cursor is in the answer field now pastes into the expression field instead.
  • Doing a "copy" when nothing is selected in either the expression field or the answer field causes the answer to be copied to the clipboard.
  • Reorganized the menus. "Convert", "Calculate" and "Debug" are now part of a new "Calc" menu.
  • Added HexColor24 output mode which shows the results in terms of a 24bit color.
