I would say: not at all; boost.format is a replacement for printf to 
make it typesafe - there's not much more about numeric formatting than 
in std C.

However, custom numeric formatting could be included into boost.format, 
though this wouldn't be the usual approach as in other languages. I 
would go this way and add an optional parameter in boost::lexial_cast 
which would result in a syntax similar to .NET and Java:

string s = lexical_cast<std::string>(1231.23, "#,#.00");

Support for numeric format strings is part of the libraries of many 
common programming languages (e.g. Java and .NET). Although they differ 
a little bit over the different implementations, I think there is a 
common base which I tried to implement.
