What exactly is a .2 tub?

We keep seeing this term within realtor magazine. 4 bedroom 3.2 baths. It is driving us nuts, we can't find what it means!

Answers:    Well I hope its just a typo since the two is right below the five, however i did find something that will help you. I found it quite funny because i too be confused.

PS its a new numbering system...
I was going to enunciate maybe its an outhouse or something equally funny, but wiki answer is exactly what are looking for... hope i gave the best answer.
A .5 hip bath is a bathroom that has a toilet and a sink but does not have a shower or a tub in it. I think it would aim 3 full baths, 2 half baths?
