numbat

List of changes for this calculator [0]. I used to use it quite a bit, but I now gravitate towards numbat instead [1]. [0]: https://www.speedcrunch.org/download.html [1]: https://github.com/sharkdp/numbat

numbat is my go-to for this: https://github.com/sharkdp/numbat

Awesome work! I've been dreaming of this project myself with a very similar stack (basically React instead of Svelte), but I'm very excited to finally have a Raycast alternative for Linux that has both consistent UI and extension compatibility. The most impressive part is probably your age, because this isn't an easy project even for senior devs! I haven't tried it yet, but I can't wait to find some time for that. I've researched applications like this for Linux quite extensively and I think you might find the following tips of interest: - For the slow extension startup issue you mentioned, consider Deno as a runtime as it has a better sandbox and is faster than Node overall. There may be some compatibility issues, but if I remember correctly most stuff is handled by the special Raycast extension libraries which you implement manually any

Try https://numbat.dev/ (https://github.com/sharkdp/numbat). It's my go-to for any engineering calculations. It can also run locally. >>> 4 weeks + 59*3 hours -> days 4 week + 59 × 3 hour day = 35.375 day [Time] >>> 5V / 50ohm -> mA 5 volt / 50 ohm milliampere = 100 mA [Current] Full syntax: https://numbat.dev/doc/example-numbat_syntax.html

I haven't had the opportunity to use this in research yet, but i liked numbat [0], as it comes with relevant common units and lets you define your own. It appeared on HN before [1]. [0]: https://github.com/sharkdp/numbat [1]: https://news.ycombinator.com/item?id=38276430

> 365·243 ought to be 365·2425 exactly: Yes. This is also how it is defined: https://github.com/sharkdp/numbat/blob/ba9e97b1fbf6353d24695... The calculation above is showing a rounded result (6 significant digits by default).

Yes. If you want to know more, you can read about it here: https://github.com/sharkdp/numbat/blob/master/assets/reasons...

I looked at Julia and Unitful.jl quite a bit when designing Numbat. It looks great. > Extending it to cover all of Numbat's functionality could be trivially accomplished in a few lines. Look, I'm not claiming that Numbat is superior. But I think Numbat might have its own little niche. And even if not, it's always good to have alternative solutions available. - Numbat is specifically designed to handle physical dimensions and units. It has a special syntax to give developers the best experience when dealing with units. You can just type "KiB" and have it be parsed as kibibytes. You can use the "->" operator to convert to other units. You can directly annotate functions with physical dimensions ("fn kinetic_energy(m: Mass, v: Velocity) -> Energy = …"). Other languages and their unit libraries might have the same functionality, but it has al

Yes. We use up-to-date currency exchange rates from the European Central Bank [1]. https://github.com/sharkdp/numbat/blob/786512175b99c195a7d5b...

> As a physicist, if you ever see units on the parameter to a trigonmetric function, you can be fairly certain something is wrong. Exactly. Which is why trigonometric functions in Numbat have the signature cos(x: Scalar) -> Scalar and only take quantities as arguments that are implicitly convertible to a scalar, like 'cos(pi / 3)', 'cos(30 deg)' or 'cos(0.5 turn)'. Whether or not angles should be considered dimensionless is actually a matter of academic dispute.
