Add float support to NumberSelector about vis-ui

[nikoliazekter]

Calling setPresicion invalidates text highlighting if input is greater than max value. Also it doens't matter if I call setPrecision(0) or with any other argument.

invalidates text highlighting

So text is deselected? Please provide SSCCE.
