in thread OT: Finding Factor Closest To Square Root

Maybe I don't understand the OP's requirements, but 36 isn't a factor of 996 (996/36 = 27.666...). I'm guessing he wants 12 (3*2*2) for that case. And 32 isn't a factor of 1000, but 25 is. etc. Am I missing something?

    Nope. Nothing at all.

    Your just witnessing me loosing sight of the OP's requirements whilst getting caught up with the mechnics of the code. :(

    I updated 432636. Does the new version look any better?

    That's the problem with hueristics--how do you validate them?

      For the case of 1994, I'd say 2 is closer to 44.65... than 997. For 1993, I'd probably go with 1 over 1e99 or 1993. For 99999999, I think 9999 (101*11*3*3) is closest. (I'm just basing this on the comments after the __END__ tag in your code, 'cause I'm to lazy to install Math::Big::Factor)

        , 'cause I'm to lazy to install Math::Big::Factor

        I think that Math::Big::Factor may be a red-herring anyway. See Re: OT: Finding Factor Closest To Square Root.
