To do it yourself, probably best to use a temp string value, created by
format "{: f}".  (Notice the space before the f, to reserve space for
the sign)  Then, slice that value to length 4 .  Finally, in your actual
format, use :5s for a format.  This should add the blanks for padding,
so other columns still line up.
