Perfect!  Amazing what's hiding under the hood.  I always prefer to do 
as much as possible with built in functionality.

Yeah, it would be more complicated and more involved to get a neat 
printout.  The engineer in me does want the field width to be 
independent of the sign, but it's a trivial matter.

BTW, is this kosher:

... I just noticed this in some of my code.  Seems to me that samples 
one and two above should throw an error because there are two 'fi' 
needed but they seem to be sharing the single one.   And sample three 
gets it right, no?
