X.X (ex. 0.1) next to snake morph, what does this mean?

[xcrafter]

I see it when people list snakes, what does this stand for?
0.1 Pastel, 2.4 normal, would be examples of what I'm talking about.

It stands for how many of what gender someone has.

males.females.unknown

So 2.4 pastels would be 2 males and 4 females.

I have 2.2.2 crested geckos, so I have 2 males, 2 females and 2 unknown.
