Hello all,

I always get a ton of good information and programs from the forums. Anyway, here's a present of dubious(?) value to everyone. This is what happens when you have too much time on your hands during the holidays! :) Please check it out:

Check to see if the number you have entered is prime. Program gives a result of "1" if prime, or "0" if not. If the number is not prime, hitting RCL 3 will give you the square root if the number has one, or will give you the lowest factor of the number. It isn't optimized or anything, just plain jane. The original number can be recalled by hitting RCL 1.

Legend:

/ = divide

SQRT = The square root
