Serialization of floating point numbers to decimal form is actually a very tricky issue once you need to support a round trip (e.g., text->double->text->double) without loss of information. It took us a long time to figure out various nuances. If you are interested, you can take a look at how we do it in CodeSynthesis XSD (see the link in the signature below). Also the following paper is quite useful in understanding of the issue involved: http://www2.open-std.org/JTC1/SC22/WG21/docs/papers/2005/n1822.pdf > Second question comes now.

We use the standard C++ streams for that (std::ostringstream).
