Use printf-style floating FORMAT string. The @var{format} string must contain
-one @samp{%f} directive, optionally with @samp{'}, @samp{-}, @samp{0}, or width
-modifiers. The @samp{'} modifier will enable @option{--grouping}, the @samp{-}
-modifier will enable left-aligned @option{--padding} and the width modifier will
-enable right-aligned @option{--padding}. The @samp{0} width modifier
-(without the @samp{-} modifier) will generate leading zeros on the number,
-up to the specified width.
