	convert a string to a Real, returns numeric::get_undefined_real() on failure More...
std::string	utility::Real2string (platform::Real, std::size_t const decimal_places)
	convert a Real to string at a number of decimal places, optionally pad left. More...
std::string	utility::fmt_real (platform::Real, platform::Size const pad_left_newlen, std::size_t const decimal_places)

	True iff haystack ends with needle. More...
void	utility::slurp (std::istream &in, std::string &out)
void	utility::trim (std::string &s, const std::string &drop=" ")
	Remove any charachters in "drop" from the front and back of the string. Use strip() for the value-return version. More...
std::string	utility::strip (std::string const &source, char c=' ')
	Return a copy of the string with leading and trailing characters removed. More...
std::string	utility::strip (std::string const &source, std::string const &drop)
	Return a copy of the string with leading and trailing characters removed Any charachters in drop will be removed For the in place version, see trim() More...
std::string	utility::trim (std::string const &s, std::string const &drop=" ")
