There is something wrong with the order of operations. When I type 2+2*2-6 i get -6 which should be 0.
I would think this might be the first unit test one would write for a calculator program.

#43Love it! This kind of stuff should be added to notepad on Windows (in an opt-in manner)!
IIRC, calc.exe (Windows Calculator) has some (limited) unit conversions built in. Better than nothing in an offline environment...

Oh there's more:
9 - 3 ^ 2 = 0
9 -3 ^ 2 = 18 ???
pi = 3.1415926536
2 pi = 5.1415926536 ???
sin(3.1415926536 radians) = -0
sin(pi radians) = Incompatible units ???

#46This is awesome! Some feature requests: it would be great though if you could have multiple sessions/tabs in stead of 1. Also a clear button would be nice.
Can’t you just select all then hit backspace? Asking for a friend...

Seems to assume + if an arithmetic operator is missing?

#48This is great, I use `bc` a lot at work (particularly when away from desk and my actual calculator) but I'll probably bookmark this to use instead.
One bit of very minor feedback:
`x^y tonnes` errors 'exponent must be unitless'. The more expected (IMO) grouping `(x^y) tonnes` works, so why not have the non-error grouping be the implied one, when no parens given?

#49I wonder when Google docs will introduce this type of feature.

#50THIS IS AMAZING. the next step is adding variables and assignments and conditionals, and you have something very powerful that can be used by just about anybody to do really interesting things. provided you have a way to integrate with other services that a lot of people use
Variables and assignments are already supported.
