Question: how much does it overlap with functionality of Boost.Format?
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. Stefan
