RE: Really big numbers

Dan,

170! = 170*169*168*...*1 = 7.2574156153079989673967282111293e+306

307 digits long.

Not quite as big as you think.

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
