Feature: Format float in show_results() regression model with float labels

I am working on regression model from image input and I am getting this king of output from learner.show_results()

The problem is that float labels are with long tails and they overlap.

I looked up **kwargs from this function up to

but could not find any possibility to format the label.
I will be happy to fix it, but I don’t have a clear understanding of the fix. Should I add some if condition with default value or add repr or str for the ItemBase in case it is float?

Waiting for any suggestion about what is the best place to fix it.
