string erase_to_last_of	(	string const &	str,
		char	ch
	)

Definition at line 23 of file string_manip.cpp.

Referenced by erase_to_last_of_tests(), and op_basename().

Here is the caller graph for this function:

string const format_percent	(	double	value,
		size_t	int_width,
		size_t	frac_width,
		bool	showpos = false
	)

format_percent - smart format of double percentage value

Parameters:

	value	- the value
	int_width	- the maximum integer integer width default to 2
	frac_width	- the fractionnary width default to 4
	showpos	- show + sign for positive values

This formats a percentage into exactly the given width and returns it. If the integer part is larger than the given int_width, the returned string will be wider. The returned string is never shorter than (fract_with + int_width + 1)
