It would be nice with some documentation of what the Math mode supports, e.g. syntax, units, functions.

It can be difficult to figure out why some lines are interpreted ok and while others fail.

How to convert between fahrenheit and celsius?

[jonatanheyman]

Yes, I've learned that Heynote is lacking some documentation. Will improve that.

Math.js (https://mathjs.org/) powers the Math blocks, so what's supported by Math.js should be supported by Heynote, with the addition of currency conversions (exchange rates are updated daily).

> How to convert between fahrenheit and celsius?

This should work:

  10 celsius to fahrenheit

[silvestrov]

Could it be made to parse "10°C" as "10 celsius" as that is much shorter?

Suggestion: mouse over on green calculated value should show value in multiple formats. E.g. "time = 4000 seconds" could show "01:06:40"

also: "today + 4 days" or "now + 1 day"

Unicode "π" should parse like "PI".

You can do that (and lots more) with Fend: https://github.com/printfn/fend/
