RE: Large number division

Suppose you entered the following calculation (not likely to happen, but 
exaggeration for the point of emphasis, right.)

999999999999999999999999999999.999999999999999999999999999999 / 
999999999999999999999999999999.999999999999999999999999999998 
        (30 digits and 30 decimal places)       divided by (30 digits and 
30 decimal places)

The value would be converted to a character string that is 60 digits long 
divided by a 60 digit number.  Clearly the answer is approx. 1, but 
because the fields are longer than the maximum number of digits allowed in 
a numerical field, how would you programmable divide this value.  You 
would have to break it up some how.



For a SLOW method, you could call a REXX procedure.  REXX can do 
arbitrary-precision arithmetic.  I think Java has some such capability too, 
with special classes for it.  Other than that, find a book on algorithms, I 
guess.
