Comment:

 Hello,

 Unfortunately there is little boost::format can do here, the issue seems
 to be that your compiler's standard library's streams and/or locales
 formats the infinity() value this way when the stream's
 std::ios_base::fixed bit is set.

 Format is merely a wrapper around <iostream>, "%0.5f" is translated into a
 certain iostream state, and a stream is used to do the actual formatting.

 I could give you the precise equivalent iostream code, if you need it to
 investigate what your std library is doing and possibly file a bug report
 with MS Visual Studio 2005.
