How to add calculations to the gnome search bar?

  • 772

I was using Gnome on PureOS for a month or so, but now I'm back on Ubuntu 18.04. The thing I loved in PureOS is that I could do calculations in the Gnome search bar. But when I type any calculations (1+2) in the gnome search bar I see no results (it says "No results" in Dutch):

I tried this gnome extension and it's enabled in Gnome tweak tool as you can see below, but I see no results (I rebooted to be sure).

Does anybody know how I can activate calculations in the Gnome search bar?

search gnome-shell calculator

  1. Best Answer

    I found this from Built-in calculator to GNOME search window

    The pre-installed GNOME Calculator in Ubuntu 18.04 is a snap application which may lack some features provided by the traditional one due to restrictions of snap packages.

    Remove the snap application by running

    snap remove gnome-calculator

    and install the traditional apt one by running

    sudo apt install gnome-calculator

    You may need to to restart GNOME shell by hitting Alt+F2, then typing r and pressing Enter for it to take effect.

  2. It works for me in Ubuntu 17.10 (and Wayland) with double parentheses, which is used also on the command line

    $ echo "$((1+2))"
3

    So try

    ((1+2))

    See this screenshot,

    enter image description here

    After an update & upgrade it works without parentheses and with single parentheses too,

    1+2
(1+2)

  3. I checked out the github page of the extension I was trying to use, which says:

    This extension is now obsolete as the gnome calculator provides this functionality since g-s 3.14

    So I installed Gnome Calculator using the Software center and now it works like a charm.
