[Calculator]Long formulas do not fit in calculator history

[Bartosz Kosiorek]

Long formulas do not fit in calculator history. This is especially visible in Portrait View and with inifinity result's number (for example (1/3=0.3333333333333)

Also Input Field is quite short and we should analyse possible solution for that

Truncating numbers will not help with all cases: for example long formula.
One of the idea was to use few lines to display history: If formula is short then we will display it in one row, if not we will use few rows.

I think we need analyse possible solutions, and select one which fit our need the best.

Proposed solution:
Introduce multi line calculations history
The history displays could be limited to 3 lines. After formula exceeds 3 lines, the three dots will be displayed.

UX Comment:

The bug highlights the need to allow for multi-line history. The proposed 3 line limit (with an ellipses '...' truncating the third line when it is exceeded) seems a reasonable upper limit.

Multiline support it is not looks good for Portrait View, when Result and Formula is in the same line. Espeically when result string is long and tooks almost whole space (eg. 1/3+99-99=0.333333333333).

My proposal is for Portrait View, separate Result and Formula (see Portrait_view_multi_line.png).
For landscape view, it will looks the same (see: landscape-view-multiline.png)

Let's go ahead and try this solution; your latest proposal matches up with portrait mode designs and addresses an issue not previously encountered with landscape mode.

Hi!

Trying this installer https://core-apps-jenkins.ubuntu.com/job/run-ap-tests-autolanding/6/artifact/com.ubuntu.calculator_2.0.258_all.click

The long operation looks fine :)
