RE: Really big numbers

Dan,

I think you trimmed out the !, try a number greater than 170!, which 
is 7.257415615307998967396728211e+306 (some precision trimmed) 
and it fails.  This is to calculate a Poisson Distribution.

a number greater than 170?  How about a 3-digit field?  ;-)

What?  You work for Microsoft?  170 digits?  Trying to set the world record
for largest prime number?

>2,147,483,647 digits

Um, is this a typo?  How would one even begin to store a number that large?
That's a one-record, one-field, 2 gigabytes file.  Oh, is it packed?  Sorry,
just 1 GB.

B,

Thanks for the suggestion.  Until I read the Class documentation I did
not realize that BigDecimal can go up to 2,147,483,647 digits.  That probably
fits the problem better than another suggestion to use REX, which works
fine, but Java is a much more acceptable solution.  I was amazed at how
fast REX is so I won't rule it out.

Math enabled RPGIV'ers,

What are some of the options for storing and manipulating
very large numbers where long float is just not large enough?
In this case to use a number greater than 170!.

Thanks,

David Morris
