Thanks for sharing! I found an amusing math bug in the basic calculator:

0 + 0.00000001 gives 1e-8 (I see you’re displaying in scientific notation, hmm— I wonder how you’re storing it internally…)

Then multiplying that by 5 gives… -39.

Somehow 1e-8 * 5 is being parsed as 1 + (-8 * 5)?

FYI the word is "converter" not "convertor" https://www.dictionary.com/browse/converter

Looks like both spellings are used: https://en.wiktionary.org/wiki/converter

Yes, both are correct spellings of the word.

If you're taking suggestions, I have a frequent need to do basic arithmetic on fractions and not many "app" calculators do that well or at all.

Buy a handheld calculator. Many scientifics since the mid 80s handle compound fractions via the "a b/c" key.

I have a couple, they work fine, but there don't seem to be that many options for apps/web.

This is very different, but check out my https://git.sr.ht/~akkartik/notebook.love

I don't have an immediate use for it, but I quite like it!

I tried 0.00000000000000000000000000000000000000001 * 2 and it gave me 0. Precision on a calculator is very important, such operations should be exact. Please refrain from using floating point operations.

It may be pedantic from me but what are you calculating that needs that level of precision?

Or more specifically, why not just use a different unit base, fixed point arithmetic doesn't come for free.

Very nicely done. If I were to tweak something....

Some have different names once you click on them.

- "Speed" is "Speed and Pace."

- "Data Size" is "Data Storage"

- "Fuel Economy" is "Fuel Consumption"

On the Data Size / Data Storage calculator, I would add kilobits, megabits, gigabits, and terabits. In addition to data storage, that might make it useful as a bandwidth calculator as well.
