LCD gestures and the Clipboard

The LCD display area accepts a number of gestures.

Figure 1: The LCD display accepts four gestures. They are distinguished by touching left or right, quick touch or long press.

Right side, quick touch: copy the displayed value (the X register) to the clipboard. The LCD blinks once to signal the operation.

Right side, long press: paste a number from the clipboard to the X register. The LCD blinks slowly once to signal the paste-in was successful, or blinks twice if it didn't work.

Left side, quick touch: show the calculator backside. It is a quick guide with some information about mathematical operations.

Left side, long press: open the Color Editor.

Number format vs the Clipboard

The value is copied to Clipboard with the configured decimal separator, and no thousand separators.

When pasting in a value, the thousand separators are ignored, and the decimal separator must be the one configured in your device's Language & Region.

If the clipboard contents cannot be interpreted as a number, paste-in won't work. This is signalled by blinking the LCD twice.

Vertical layout, big-screen devices

The vertical or portrait layout can be more practical if you like to use your phone in portrait orientation. If you don't like it, go to Settings and lock the orientation to Landscape.

This app adapts to any screen or window size. On iPad, it can run fullscreen, split-screen, or in windowed mode. The layout adapts automatically to the aspect of the available space, unless you lock the orientation in Settings.

This app can run on MacOS, in windowed mode, offering an almost-native user experience.
