385 numberp
printed representation of the number. If the number
contains fewer characters than min-columns, the number
is right-justified within the array. If the number contains
more characters than min-columns, min-columns is
ignored. An error is signalled if the number contains
more characters than the length of the array minus
at-index. The default is the first position, position o.
The following example puts 23453243 into string starting at character position
5. Since min-columns is 10, the number is preceded by two spaces.
(let «string (make-array 29. :type 'art-string :initia1-va1ue #\X»)
