Rounding values

[RCatersels]

It would be nice to have the option to set the decimal precision. Now values are either to long or to short. Even when creating a rounded value 20,50 it comes out in the tooltip as 20,5.

Furthermore it would be nice if you could add a before and an after text. This way you could show for example € 20,50 or values like 200,50 km (see also the bootstrap input addons where you can set these values).
