what do these numerical prefixes mean?

for example:
1.0 Jungle Carpet Python
1.1 Ball Python
0.0.2 Green Tree Python
etc etc
yes, i'm new at this ;)

a quick search will yield this answern but here goes
1.0 mean 1 male
0.1 mean 1 female
0.0.1 means 1 unsexxed
so 1.2.2 would mean 1 male. 2 females. 2 unsexxed

thanks... yeah i actually tried searching to no avail. i guess i couldn't hit what the prefixes would be called - tried numeric, prefix, heading, FAQ, etc
