float number + music copyright

Thank you for clearing question 2 up.
But there's still the question what the "f" does at float numbers, since they still work without it.

Without it angelscript assumes the numbers are doubles, which are effectively a more "precise" version of a float (oversimplifying things a little, feel free to read up on floating point if you want to know the exact difference). In the end there won't really be any negative effects from putting doubles where you should have floats, but the conversion will sometimes give you warnings about loss of precision, which can clutter up the errors pane a little.
