I agree.

So ...

     '{0:10.20,f.2}'

would become...

     '{0:10;20,f.2}'

Works for me.

I think this would be better because then decimal places would be 
recognizable right off because they *would* have a decimal before them. 
And nothing else would.  And min;max would be recognizable right off 
because of the semicolon.

And I can't think of anything that would be unique and work better.
