   No, no, no....   It may and should be used for financial calculations,
          so true,
but it may ALSO be used for a general purpose high precision (and) 
arbitrary precision decimal floating point. Otherwise it might as well have
been patterned after the fixed width standard.  It was patterned after 
Cowlishaw's extension. 

Why do you say only financial?
