The problem with relying on purely sprintf-style formatting is you're
missing the localization provided by the streams classes (unless *I'm*
And if you want to parse the numbers, again streams would be the logical
choice in C++.
That's why I was suggesting something akin to the lexical_cast<>
templates I have available. They are easily extensible to include input
as well as output, so would provide a natural bridge between text
representation and float/complex/etc. data values, and even extend to
other data types like dates, money, etc.
I use something similar in the libsimple/libgtklink libraries (also
available, I believe) which provide simplified interface/link between
data vars and widgets. In particular, I have a translation class used
with the entry fields to provide translation to/from the Gtk::Text
