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?3 votes
iOS 11: If screen is splitted with another App together with Calca, when trying to input text on Calca screen, the top-part 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.1 vote
I think it would be very nice to have the ability to get, at least, linear interpolation.1 vote
Hi, the extra keyboard row doesn't display properly when in portrait orientation, it gets both sides chopped off.
the decimal character for de-CH 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
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.1 vote

The graph panel / sidebar presentation is generally icky. The program itself is GREAT --- the language is great, it's all great. Except for visualization.4 votes
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.4 votes
I find trying to put tabular data into a document in a way that makes sense quite difficult. Various markdown flavors support this.1 vote
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.5 votes
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.6 votes
Approximation of F(z) from z
For a given z, to find F(z), the following Hastings routine
#entrar el valor de z para el qye se desea encontrar Prob[x<=z]
Valor de z
k= if z < 0 then -z else z
Prob= if z < 0 then 1-F(z) else F(z)
Aproximation of z from F(z)
#entrar el valor de P[x<=k] en H
H1= if H<=0.5 then H else 1-H
zinv= if H1<=0.5 then k else -k
zinv => 1.64521 vote
When trying to derivate like this:
f= x^3 + 4x^2 - 5x + 1
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

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
bike repair(p1) = 1000
house(p0) = 100
car fixing(p1) = 9000
window(p0) = 200
expense => ...
and p0 => should be sum of all p0
p1 => should be sum of all p11 vote
- Don't see your idea?
