I very much like the idea of this calculator, particularly since it has a python implementation. However, there are a couple of caveats - it uses binary arithmetic, though since release it seems they've improved the accuracy, and also I'm not sure how free this license is[1]. For something that isn't open-source, but uses RPN and has quad-precision binary-encoded decimal precision the DM42 looks really nice[2].

> I'm not sure how free this license is No need to wonder, if by "free" you mean "free as in the fsf definition". This violates at least freedom 4 by having the ND clause. You can't redistribute your modified version.

SwissMicros calculators are beautiful, I have a 15L and will be adding a DM42 as soon as they are available. If you are thinking of ordering any of their products, you will not be disappointed!

>I'm not sure how free this license is. There is an ongoing discussion about what license to use for what part of the project, and what is the rational behind such and such choice. See this Github issue: https://github.com/numworks/epsilon/issues/38 https://github.com/numworks/epsilon/issues/38
