Qalculate! Reviews and details

• Frink

  Interesting project. I use command line Qalculate [1] for this (has a very similar feature set to Frink AFAICT) and Pint [2] for scripting. I feel like unit-aware calculators are hugely underused by physical engineers, it's the same idea and benefit as type safety but they're virtually unheard of, everyone just uses excel. Having guaranteed dimensional correctness is so great for the early design stage, it makes... - Source: Hacker News / 7 days ago

• "A calculator app? Anyone could make that."

  I use qalculate, it behaves well enough for my needs. https://qalculate.github.io/. - Source: Hacker News / about 1 month ago

• Students, what features would you like to see on Windows 12?

  1) a scientific calculator with history and variables with a UI similar to https://sourceforge.net/projects/alt1-calculator/ that also can do units like https://qalculate.github.io/ 2) a tiny text chat direct message program that is similarly as easily accessible at Atl1 3) a minimalist dock of as many instances you would like similar to https://punklabs.com/rocketdock, and like where WIN opens the start menu, WIN...

• Paint on Windows is getting layers and transparency support

  Qalculate is my go-to for cross platform calculator that is useful and is not limited to the most basic +-*/ operations. https://qalculate.github.io/. - Source: Hacker News / over 1 year ago

• Keisan Casio is shutting down

  If you want a self-hosted replacement for Keisan I strongly suggest looking at Qalculate! https://qalculate.github.io/. - Source: Hacker News / over 1 year ago

• GNU Units

  I personally use Qalculate (https://qalculate.github.io/), specifically their CLI version for this purpose. I'm not sure how well it compares to GNU Units, but it works well enough for my needs; and it's fairly simple using English-like syntax. - Source: Hacker News / over 1 year ago

• Ask HN: Do you still use a hand held/desktop calculator?

  On the terminal, I use `qalc`[1]. It's a nice natural language calculator that does arithmetic, solves quadratic equations/linear systems, does unit conversions and even a bit of calculus. Combine it with a cli graphing tool and you can do pretty cool things. Anything more complicated I'm probably ok with latency, so I open up wolframalpha and enter it there, again, in natural language. [1]... - Source: Hacker News / over 1 year ago

• [Conversion] I need an explanation for this question please

  Btw, download qalculate.github.io and play around with it a bit. I use it for basically all the physics I do. Complete lifesaver. Source: over 1 year ago

• Calculator for sway

  Personally I use http://qalculate.github.io/ since I end up having to do unit conversions often, it's pretty handy for that. Source: over 1 year ago

• Here's the minimum time it'll take to overflow the "Total damage" variable on the dummy target

  Btw: http://qalculate.github.io/ is nice. I use CLI version to fix my general math incompetence. Even does units nicely, for example, "how long it would take to download 82GB game on 50Mbit connection":. Source: almost 2 years ago

• This week in KDE: The best Plasma 5 version ever

  Https://qalculate.github.io/ <- this calculator is great! It has reverse polish notation (RPN) capability. Really, everything you might want in a calc program (and a plasma widget is available too). Source: about 2 years ago

• Good scientific calc for windows?

  Have a look at Qalculate. It's a pretty decent calculator app rather than a fully fledged mathematical or programming language. It can do algebraic calculations and graphing as well as matrices and vectors and calculus. It's also open source, so it's free. Source: about 2 years ago

• Try it ;3

  Qalculate can do 40 000 000! ≈ 3.776664041 × 10286710624 but it takes about 40 s and a gigabyte of memory. I can’t be bothered pushing it much further than that. Source: over 2 years ago

• 'qalc' is awesome!

  I agree!!! It has gui versions, qalculate, but (of course) I prefer the cli version. The website is https://qalculate.github.io/. Source: over 2 years ago

• Show HN: I made a web-based notepad with a built in unit calculator

  Note: I had this response typed up but didn't submit... One related app that I absolutely love is Qalculate![1] (yes, it has a built-in exclamation for default enthusiasm :) ) It can do cool stuff like converting N (newtons) to kg.m/s^2 when you specify units as ?kg. It also converts units like 1kW x 1year = 31.55... GJ It's fantastic for engineering and specially back-of-envelope calculations. This notepad aspect... - Source: Hacker News / over 2 years ago

  Qalculate can do RPN on windows. It can handle units and do algebra and it's open source. Source: over 2 years ago

• Why on earth is my calculator app using 67 megabytes of compressed memory?

  I was about to say "I just wish Qalculate would work on a Mac", but apparently someone actually got around to creating a homebrew port: brew install qalculate-gtk. Source: almost 3 years ago

• TIL that Texas Instruments has gone back and forth on how their calculators handle implicit multiplication with ambiguous notation, e.g. 8÷2(2+2). Different products will give different answers.

  The example in the link was specifically ax/by. And my favorite calculator, Qalculate!, treats implied multiplication differently:. Source: almost 3 years ago
