[gentoo-user] [OT] In search of a certain program...

Hi,

in a video I saw someone using a neat little commandline tool (no gui)
called 'qcalc', with which he performs some interesting calculations.

I searched the web for it and found this link
https://state-machine.com/qtools/qcalc.html#qcalc_linux
but it is another type of calculator and it has a gui.

Does someone knows of this commandline tool and what
package/archive/... it is contained in?

Thanks a lot for any help in advance!
Cheers
Meino
