Definitions

resetiosflags	clears the specified ios_base flags (function)
setiosflags	sets the specified ios_base flags (function)
setbase	changes the base used for integer I/O (function)
setfill	changes the fill character (function template)
setprecision	changes floating-point precision (function)
setw	changes the width of the next input/output field (function)
get_money (C++11)	parses a monetary value (function template)
put_money (C++11)	formats and outputs a monetary value (function template)
get_time (C++11)	parses a date/time value of specified format (function template)
put_time (C++11)	formats and outputs a date/time value according to the specified format (function template)
quoted (C++14)	inserts and extracts quoted strings with embedded spaces (function template)
