Calculator widget

Calculator puts a clean basic calculator on your desktop: digits, the four operations, percent, sign toggle, decimal point, backspace and clear. It follows math precedence, so 2 + 3 x 4 gives 14, and the line above the display shows the expression as you build it.

Click it once and type: the keyboard covers everything, with Enter for equals, Escape for clear and Backspace to fix a slip. Every finished calculation lands on a history tape under the keys, and clicking a tape line loads that result back into the display. The tape and the last result survive restarts, stored locally on your machine.

Hide the tape for a compact keypad, tint the operator keys with your theme accent or a custom color, and pick a solid, transparent or hidden panel.
