Rounding numbers is probably one of the topics in primary school. In school, we’ve learned that half rounds up, anything less than half rounds down. For example, 0.5 rounds to 1, but 0.4 rounds to 1. Duh, I’m stating the obvious you think. It only came to my attention that this is NOT really the default behaviour in a very popular programming language: Python.
Here, is a simple example to try in your own Python console.

I’ve explored the option 1, however, I soon ran into the problems with the Model/View/Delegate architecture which means I would have to implement native plugins/add-ons in order to use ListView. Not to mention the framework itself is still heavily under development.
As for option 2, I’m not a web frontend engineer and personally I much prefer something that is native (or looks and feels native at least). For the third option, it feels a bit overkill but it is a possible way out.
Luckily I don’t have to do the re-implementation, because I’ve managed to get the core functionality bundled into a single JS file which works flawlessly in the QML environment. Before I start diving into the details on how you can make your npm packages work in QML, I have to emphasise that there are many limitations in the QML environment and it’s very likely that only a small subset of the npm package that you’re interested in is going to work.
