String formatting in .slint

[Blquinn]

Hello all,

I was wondering if there's anyway to format a float in .slint markup, to avoid having to do the formatting in my rust code.

I want to do something like format!("{:.2}", 2.342342525) in rust. I'd like this in the .slint file because this is how I am displaying the model, so I think it makes sense to go there and not in some additional field on the model.

Follow up question is, can I just insert a snippet of rust code into a slint file somehow?

Right now you can do: "" + (Math.round(2.342342525 * 100) / 100)

We do need better way to do such formatting, and i think it could be done in a locale definite way through the @tr() macro in the future.

(slightly related: #3597 and #586 )

Ok, I will go with that approach, thanks!
