Numbers in member signature posts

Hello, this is a very noob question if you cant already tell, but what do the numbers mean exactly in the bottom signature of some members when the post or on their profile??

for example someone has 1.2 Ambilobe, 2.0 Parsoni

what does the 1.2 mean?? thanks in advance for your help

The first number is males the second females and the third is unknown (like new babies)

1.2 would be one male two females

thanks Cait
