Newbie Question [lol]

Can anyone explain why everyone list there collection by numbers with decimals.

ex. 1.0 Ball python, 0.2 Spider and so on.

Your probably thinking wow this kid is stupid but I can't learn if I don't ask. :P

the sexes 0.1 =female, 1.0 = male, 0.0.1 = unknown

oh ok thanks for clearing that up but what about other numbers than 0 and 1, like in your sig "2.6.1 Normals"

2 males
6 females
1 unknown

Cool now I get it thanks for your help :)

I was wondering the same thing when I started on here a few days ago. I assumed that it was describing the sex of the snakes, but I wasn't positive.
