xcalc

From ArchWiki

xcalc is a scientific calculator for the X Window System.

Installation

Install the xorg-xcalc package.

Configuration

There are several options you can set in your X resources files to make xcalc look much better than the default black text on white background. The position, label, function and colour can be individually changed for each button. See xcalc(1) § CUSTOMIZATION for more information.

Theming

xcalc has a built in theme emulating the looks of a Texas Instruments TI-30. See xcalc(1) § COLORS on how to enable it.

If you just want some nicer looking colours, you can try out this theme.

Change the division label

You can change the division symbol to a forward slash if you prefer.

XCalc.ti.button35.label: /

Desktop entry

xcalc will not show up in the application menu since it does not come with a desktop entry. To make it appear in the menu, you can add a desktop entry.

~/.local/share/applications/xcalc.desktop
[Desktop Entry]
Name=XCalc
GenericName=Scientific Calculator
Comment=Scientific calculator for X
Exec=xcalc
Icon=accessories-calculator
Terminal=false
Type=Application
StartupNotify=true
Keywords=calculator;scientific;
Categories=Utility;Calculator;

The menu entry will appear as XCalc in the Utility > Calculator application list.
