Standard C++ provides a few functions to convert a double or float value to string, namely, sprintf, stringstream::operator<<, snprintf, to_string, to_chars and format.

This talk concerns what goes on behind the scenes, i.e, the algorithms which these functions might use to do their job. Curiously, many of these algorithms have dragon-related names like Dragon, Grisu, Errol, Ryu and Dragonbox.

Here mythology meets technology and we shall introduce the new dragon that has just arrived in the den.
