numbers in sigs

Im not sure if this goes here, if not sorry.
What do the numbers in people signitures mean? like the 1.0, 0.2

First number is males, second is females, third is unknown sex. :)

So if I have 2.5.1 normals, that means 2 males, 5 females, and 1 unknown sex.

oh thank you for clearing that up for me
