Hi

I read the documentation and looked for some examples but I was not
able to come up with a format string to do this:

Format a double using desired grouping char and decimal separator.

So 1234567.89 should print 1,234,567.89

First, how can I specify the usage of the grouping char ? sprintf uses
the ' char but it gave me invalid format string every time I tried to
use it.
Also how can I specify the grouping char and decimal separator ? By
setting the locale ?

An example would be great.

       std::stringstream ss2;
       ss2 << boost::format ("%|.2f|") % src.get_valor_total ();
       String svalor_total = ss2.str ();

Thank you in advance for your attention,
Mau.
