* \brief locale-agnostic conversion functions from floating point numbers to strings
*
* Depending on the system locale, a different decimal seperator might be used
* for floating point numbers. This is often not wanted for internal (ie non-user
* facing) purposes. This module provides conversion functions that use std::locale::classic()
* (i.e. the default if no locale is set on the system).
