Something like foo = rand(1:100) gives foo a random number between 1 and 10026 votes
I cannot find any way to undo some editing in IOS.
If it is implemented please document it.
Otherwise I think that it would be essential to at least have a way to undo recent edits or to revert to a previous version of the file. I had a complex calculation that I managed to seriously corrupt on my iPhone, while trying to change the value of an input variable and I could not find any way to go back...
Thanks for the amazing job!28 votes
It is not implemented, but will be.
Should be able to define the equivalent to an #include operator referencing another calca file. Then it would be possible to reference the functions, and variables defined.17 votes
I often find myself needing time calculation, such as the number of hours between midnight and 9:30am. Or the number of days between 25th October 2013 and 25th December 2013.122 votes
I was trying to set up a countdown calculation (days until x, unless y takes longer) but couldn't figure out how to grab today's date from Google, or how to input another date to compare it to. Not a vital feature, just a possible one.30 votes
I plan on adding more date and time functionality to make this easier.
its really anoying to type "=" and ">" everytime to compute a calculation.So i made a autohotkey script to make it work just like mathematica (Shift+Enter Style).
Here is my script.You press Shift+enter:
IfWinActive ahk_class WindowsForms10.Window.8.app.0.129c866
This script will only work when Calca window is in focus.Eventually i would want this functuanality to be baked in Calca.I think its really convenient.28 votes
Add minimum, maximum, average, and sum functions for a list of variables/numbers (maybe standard deviation, etc also)
Be nice to find the max/min of a list/array of numbers or variables, such as x = Min (x1, x2, x3,…) etc.33 votes
It would be helpful to me in using Calca as a scratchpad in programming and sysadmin work if I could use binary bit-shifts:
4 << 1 => 8
8 >> 1 => 4
I know this runs into problems with the sign bit (bug filed), but anything would be better than nothing.33 votes
As in the ability to import/include another file..I am thinking simply by filename, and it would look in the relative path of that file. Perhaps this may be a little overboard for this kind of tool, but I was thinking in terms of having common sets of units / functions etc you may use across a set of files.53 votes
y = 2z + 1
z(3) => 1
z(3) * 5 => 5*z(3) //This should be 585 votes
Tapping at the end of a line which ends in a number selects the number, no way to add text to the end of the line.11 votes
I will be turning off the tap a number feature to prevent these kinds of problems.
Beyond just Greek symbols, I'd love to see Calca produce built-up (or at least linear) equation formatting. (see http://www.unicode.org/notes/tn28/UTN28-PlainTextMath-v2.pdf)
it'd be cool to consume that markup as input also. :)
keep up the great work!35 votes
I don’t know how advanced I’ll get, but I love these.
Provide a repository where users can contribute and share their favorite functions to help quickly extend Calca's capabilities through reuse of proven solutions.12 votes
Add an easy way (button/syntax) to copy the result of the previous calculation to the current cursor.31 votes
Is that possible? If so, I would like to know how.
If it isn't, Make that happen. Please.13 votes
I have been meaning to add arbitrary precision arithmetic to help with this and cryptography.
Sure, it’s just one less character, but typing => all the time is inefficient, especially to type `=` which is at an awkward pinky location on the keyboard. The iOS app gets it right, with a `=>` shortcut button.34 votes
ctrl+space to try to auto complete variables/functions/etc (with optional dropdown).14 votes
When I use an external keyboard, Calca still auto-scrolls such that the cursor is near the top of the screen. It seems impossible to type with the cursor near the bottom of the screen, so the extra screen real-estate gained by using an external keyboard is wasted. If I two-finger scroll the text, it scrolls right back as soon as I hit a key.15 votes
Ah yes, I didn’t take into account external keyboards. I’ll try to get this fixed in the next update!
filter(x > 2, [0,1,4,5]) => [4,5]
With filter, map, and reduce, you'd have the basics of functional programming.8 votes
Specifically, means and std dev’s? Pass a series in and then do average(series), std dev(series), etc.16 votes
