Fix currency units in standard library functions
Normal units work with library functions; this works:
floor(5.46 m) => 5 m
But, this does not:
floor($5.46) => floor($5.46)
I can workaround, by doing something like:
add$(x) = $*x
rem$(x) = x/$
floor$(x) = add$(floor(rem$(x)))Can it be fixed?

[bug] keyboard partially visible on iPad 9.7 portrait split screen mode
iOS 11: If screen is splitted with another App together with Calca, when trying to input text on Calca screen, the toppart of the added–Calca–keyboard (with symbols, numbers and so on) is only partially visible on Calca’s side of the screen. The other part stays hidden by the other app which shares the screen with Calca. This makes the added part of keyboard unusable occupying precious screen space.

Add interpolation functions
I think it would be very nice to have the ability to get, at least, linear interpolation.

bug in deCH language.
hi guys
the decimal character for deCH is wrong. In Switzerland we write 1'000.99
The decimal delimiter is a . and not a , as it is actually done in calca. can you please correct this bug?thank you and best regards

Give Calca some more multilingual support
If Calca presents math into something more tangible, into words that are easier to understand, Calca should support multiple languages outside of English. Maybe Chinese support for instance.

Inline graphs ala other notebooks (Python/Jupyter, Mathematica, etc.)
The graph panel / sidebar presentation is generally icky. The program itself is GREAT  the language is great, it's all great. Except for visualization.

Setting a Variable to be used across multiple files.
I love this app. It replaced the majority of the reasons why I have spreadsheets. I would love to see a way to set a value of a variable and make it global. Meaning I could use that value in a different file.

Support inline tables
I find trying to put tabular data into a document in a way that makes sense quite difficult. Various markdown flavors support this.

3D Plot
Please do a 3D plotting function, for functions like z(x,y) = x^2 + y^2 etc. So you can see your function in 3D.

Make it work with Bear/ DayOne both support markdown
Calca concept is brilliant as was looking for something like that for long time. It would be super nice if i could easily export the notes from calca to Bear and / or Day One.

Derivating twice and plotting glitch
When trying to derivate like this:
f= x^3 + 4x^2  5x + 1
der(f(x),x)=h
der(der(f(x),x),x) = j
f => x^3 + 4 x^2  5 x + 1
h => 3 x^2 + 8 x  5
j => 6 x + 8
plot (f,j,h, 5..5)The h function won't plot.
Tried unnesting the derivations as well but it not help.
Please fix this.
Great program by the way!3 votes

Support for TODAY Function
It would be nice to support the following examples (let's suppose Today's date is 10/30/2016

i liked your finance example, but if there could be a way to tag each item and get tag based summary it will be great
say
expense +=
bike repair(p1) = 1000
house(p0) = 100
car fixing(p1) = 9000
window(p0) = 200expense => ...
and p0 => should be sum of all p0
p1 => should be sum of all p11 vote
 Don't see your idea?
