[SOLVED] Calculator with a save or retention feature

Post by ineuw » Sat Jun 02, 2018 7:16 pm

My favourite Windows calculator is SPEQ and I am looking for a Linux desktop calculator that has similar features. Essentially, it works on a built in unstructured "notepad" display and performs the calculations when the Return key is pressed. The builtin default screen retains the data between sessions, or one can save it as a file.

Well it's a lot more than just a calculator, but I just use python for this. And it has some wrinkles, like needing to use a decimal to insure floating point arithmatic, so that you don't get, for example, 7/8=0.

You are right, but unfortunately I am just trying to take baby steps with python.

Qalculate might fit your needs. I use the older version available in Synaptic Package Manager.

Thanks, I am looking at it right now, it's a lot more than need, nevertheless I may be able to use it. It's been awhile that the software was updated. It's mentioning currencies which no longer exist because of the Euro.

You may need to download the source code of the latest edition from their website and compile it. (don't forget to have build-essentials installed prior to compiling)

Yes, tried compiling as my first option, after installing all the dependencies, but there is a bug in it. So, I installed it from the Software centre. But now that I think of it, since the dependencies are already installed from the centre, I should try to compile it again.

Sorry my first reply didn't make it. I looked there as you have, but the app is only for Windows, although it's easy to misunderstand with all the surrounding and confusing info boxes.

Hi ineuw,

I just read your post and the good replies to it. Here are my thoughts on this as well.

There are a lot of calculators available in the Software Manager or Synaptic Package Manager (SPM) and elsewhere. There are also some really good posts in this forum on this topic.

One of my favorite calculators beside "Kcalc" that has a printing calculator tape that can be saved is "superbcalc" a Java based application that works great under Linux and all other operating systems.

phd21, it certainly helped. It is what I was looking for. Qalculate is a bit too match for me. Thanks for the advice.
