format() should work with the same types of parameters that printf() works with
( http://www.cplusplus.com/reference/clibrary/cstdio/printf/ ). That should
allow you to set the precision that you want, but I don't believe that it does
anything with commas. If you want that, I believe that you're going to have to
code it yourself.
