Well... PL/I-F has a STERLING data type for pounds, shillings, and pence (LSD). Now that's not decimal! Actually it's an example of the more general idea of mixed-base number systems, of which time/calendar representations are the most well known. The APL language has convenient and general operators for dealing with mixed-base data.
