It would be great if we could set the fraction digits for the displayed values even if scaling is not enabled.

When the scaling is not enabled, the displayed value is the one provided by the plug-in through the VST.AU interface... It's a text string, I've no idea about its meaning...
So I could detect that the text contains only a numeric string and tweak it, but...

So how does scaling work? Isn't there converting text to number involved, too?

The scaling is a simple rule of three. When scaling is activated the wrapper does not use the text string provided by the plug-in, but use instead the [0..1] real value and scale it to fit the specified min/max values.

Ah ok, so the plug-in actually sends two values... a number and a string.

Yes indeed. The number is used by the DAW/Sequencer for automation and the text is usually a copy of what is displayed on the plug-in GUI, but not always...
So we can use the number and scale it when the text is bad. But if the plug-in is done well, the text value is more relevant.
