#qalculate — Public Fediverse posts

The other day I put some more work into my KRunner calculator plugin.

The built-in calculator can't do currency conversion with "to", can't solve equations, can't handle unit arithmetic. kqalc fixes all of that.

What it does:
· Math: qc 2+2, qc sqrt(2), qc 2^64
· Currency: qc 5000 GEL to USD, qc 100 EUR to KZT
· Units: qc 100 km/h to mph, qc 180 lbs to kg
· Equations: qc x^2 = 9

Just open KRunner (Alt+Space), type "qc " and your expression. Select a result to copy it to clipboard.

Available for:
· Arch (AUR): paru -S kqalc-bin
· Debian/Ubuntu: APT repo
· Nix: nix run github:noctuum/kqalc
· From source (Go)

Holy mackerel, I had no idea #qalculate could do this kind of stuff!!!

rld@Intrepid:~$ qalc
> 2^24 seconds

  (2^24) seconds = 194 d + 4 h + 20 min + 16 s

> 2^32 seconds

  (2^32) seconds = 49710 d + 6 h + 28 min + 16 s

> 2^32 milliseconds

  (2^32) milliseconds = 49 d + 17 h + 2 min + 47.296 s

> 80 fahrenheit to celsius

  80 fahrenheit ≈ 26.66666667 °C

> 

This could nearly replace #WolframAlpha for me!!!

@vivi I'll also recommend qalculate

See https://f-droid.org/packages/com.jherkenhoff.qalculate

Does base conversion, unit & currency conversion, even implicitly, so you can add, subtract, multiply, divide etc many measurements with different units and it just figures it out.

It's a lovely app, also available as a GTK version for desktop (I'd recommend that one) and a Qt version (imo looks worse, even on KDE)

#KCalc es un dolor de usar. #Kalk tres cuartos de lo mismo. Pero #Qalculate parece que mola la gramola. Y además tiene interfaz hecha con los dos marcos predominantes: Qt y Gtk.

Tiene bastantes cosas.

So I gain Vorzugspunkte at a rate of just over 69 μHz, and that's only 69 days till I achieve the remaining 414 Vorzugspunkte, which will be within the calendar year :neocat_happy_blep: :train_pats:

Actually, considering I've already gained 6 Vorzugspunkte today, I'll finish a day early :hehe:

I just found out they finally ported Qalculate! to Android

https://f-droid.org/packages/com.jherkenhoff.qalculate

This thing does calculations with units, basically allowing you to divide, multiply, add, and subtract different units from one another, and it gets the units all correct
You can even do stuff like "+ now" to offset an amount of time from now, and get a time-stamp in the future.

This is very, very useful; give it a try :3

I didn't know #qalculate has been ported to #android
Nice, finally a FLOSS competitor to HiPER Calc Pro :)

I recently discovered #Qalculate and it is really cool! Unless one can get a #tinspire or #ti84 on #linux I'm not sure what better #calculator out there.

With qalc / #Qalculate, 2e + 1 is different from 2e+1. 2e + 1 means (2 × e) + 1 ≈ 6.436563657, but 2e+1 means 2 × 10¹ = 20. Very unintuitive and error-prone.

"CAS" generally stands for a "Computer Algebra System". It encompasses statistical packages and programming languages like #Maxima, #Octave, #R, #Scilab, #Sage, #KAlgebra, #Qalculate!, #Python, #Julia, #Lua. You can use them all concurrently in multiple #LabPlot's notebooks.

Please, see the attached screenshot. In this case, Python 3.12.3 is available in LabPlot on a Ubuntu machine.

Spent a couple of hours this morning fixing low-hanging fruit, broken third-party #pkgsrc software on #illumos.

#taglib uses conflicting offset_t type.

#gst-plugins1-base fails to include sys/stat.h for S_* macros.

#capstone doesn't handle non-const getopt.

#opencv uses ambiguous ceil() call.

#qalculate and #xscreensaver use conflicting "sun" define.

#qgpgme uses conflicting "single" type.

#mbrola has incorrect endian detection and is not MAKE_JOBS safe.
