pub fn format_printf(fmt: &str, args: &[Value]) -> Result<String, String>Expand description
Formats args using a C-style fmt string.
Supported specifiers: %d %i %f %e %g %s %%.
Flags: - (left-align), + (force sign), 0 (zero-pad), (space sign).
Width and .precision follow standard C printf conventions.
Escape sequences \n \t \\ are also processed.
Octave behaviour: if args is longer than the number of specifiers the
format string is repeated until all args are consumed.
