template<class T >

string util::StringFactory::floatToString	(	const T	xd,
		const int	width,
		const int	precision,
		const char	format
	)			[inline, static, protected]

Convert float/double to string

Parameters:

format,:

char to select the _floatfield_ format flag 'd': default floating-point notation 'f': fixed-point notation 'e': scientific notation

References error_text, and factory_text.

template<class T >
