  • My thousand dollar iPhone can't do math
    Qalculate is my favourite REPL-like calculator, although it unfortunately lacks an iOS app. It feels similar to using an HP 48-series calculator. Numbat is similar, but more CLI/REPL-focused, and with more of an emphasis on being a programming language. - Source: Hacker News / 7 months ago

    Https://qalculate.github.io can do this also for as long as I've used it (only a couple years to be fair). I've got it on my phone, my laptop, even my server with the qalc command. Super convenient, supports everything from unit conversion to uncertainty tracking The histogram is neat, I don't think qalc has that. On the other hand, it took 8 seconds to calculate the default (exceedingly trivial) example. Is that... - Source: Hacker News / over 1 year ago

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 / over 1 year ago
