Exciting to see an open source Rust WASM project as reference for us folks who are interested in playing around with it. Thanks for the cool work!

Re: Show HN: NoteCalc
#52On macOS, there is the excellent Numi app Sadly I haven't found any equivalent for iOS (iPhone and iPad): it would definitely get my money!
Numi would be my favourite of all these kind of calculators on macOS, if it wasn't for the lack of unit calculations[0], e.g density = 2 kg / 3 l, mass = 10 dm^3 * density [0]: Not sure of the actual term in English
I think the term in English is dimensional analysis

#53This is amazing. Doesn't feel like a web based tool at all. Can even do bitwise operations that's just great. Can there be a programmer mode where I can use & and | instead of AND and OR? Not a deal breaker though. It's going to help a lot in day to day bitwise stuff

#54Something like this exists for emacs as well: https://github.com/sulami/literate-calc-mode.el

#55Very nice app, I really liked it
Re: Show HN: NoteCalc
#56Nice. What I really want, though is a CLI calculator (something like bc or ipython) that would be clever enough to handle stuff like 1000!/999! (increase the number of digits if python will be able to do that: I hope you get the idea). I cannot treat seriously a calculator in 2020 that actually tries to evaluate expressions numerically, while representing numbers as floats or int32.
Multiplying matrices and stuff is nice, but I don't think I really ever needed that. But simple combinatorics and other calculations that involve large numbers and lots of simple operations (like powers), but are perfectly calculatable without losing precision on a piece of paper — plenty of times. It's annoying that I can calculate on a piece of paper something my calculator cannot.
Other than that, maybe some operations over physical units/unit conversion and some embedded city/timezone DB, and I don't think I can ask more of a calculator.

yeah why not :) I added it to my todo.

Have you tried isympy? It handles your factorial expression easily.

Originally NoteCalc used a library for handling arbitrarily large numbers.
Unfortunately, some operations were so slow that as a quick fix, I replaced the library with a lighter one without dynamic allocations (which is 96 bit integer with 28scale).
This serves well the primary goal of NoteCalc so I did not spend more time on it yet, but I am on the same page as you, and if NoteCalc will be feature-complete, I will give an other shot to arbitrarily large calculations/precision.

#60This is soooo nice. I wish there was a +10 option on HN - it'd be the first time I'd use it!
