Admittedly maximum is not correct; however, minimum is not right either.
The 10 is the desired (or target) width. Fixed width prints are commonly
used with very legacy systems that die a painful death when fixed width
strings are parsed by index and a field has spilled over a column. The
point is that the format returns a string that is longer than the desired
length when a perfectly valid version meets both the format and desired
length (making it more correct). The desired length should only be exceeded
when no solutions can be found. Note the below statement parses without
error. For this reason I feel this is a valid but minor issue. By using a
regular expression or slicing the desired result can be achieved, but with
extra code.
Thanks for the quick response!
