[Bf-funboard] Limits on size

[Kent Mein]

In reply to Vania Smrkovski (vania at pandorasdream.com):

Hi Vania,

The whole reason for the size limits are because of the math involved.
There is a whole field of computer science that deals with the fact that
math on a computer is not the same as your plain old every day math.
pie on the computer is not pie, and there are all kinds of extra things
that just plain don't work very well on a computer.

You may do some math operations that are suppose to equal 0 and instead
you get .000000000000000001

The computer imposes limits because it has limits on how big a number can be.

As stated in earlier comments just using the limits that are there you can
get strange results removing the limits will just let you get further into
the range of messed up math, it will not solve your problem.
The numbers may need a review and could probably be tweaked a little but
they are not just abitrary numbers that were picked out of a hat.

Sorry,

Kent

P.S. (I do think it would be nice to have longer names as you mentioned)
