The following example executed from the DOS shell illustrates the action that takes place with/without the digits argument ( "--->" denotes the result):

say d2x(672850) ----> A4452
say d2x(672850,0) -->
say d2x(672850,1) --> 2
say d2x(672850,2) --> 52
say d2x(672850,3) --> 452
say d2x(672850,4) --> 4452
say d2x(672850,5) --> A4452
say d2x(672850,6) --> 0A4452
say d2x(672850,7) --> 00A4452
say d2x(672850,8) --> 000A4452
say d2x(672850,9) --> Invalid argument to function
