TITLE: Is it possible to have multiple decimal points in a number?
QUESTION [35 upvotes]: Is it ever possible to have multiple decimal points in a number? If so, how?
For example is the value 1.1.2 possible?
This is a question posed purely out of curiosity.

REPLY [2 votes]: We could if we only decide to ! (even an infinity in this $10$ protuberances alien notation :-))
$$\pi=3.7.15.1.292.1.1.1.2.1.3.1.14...$$
$$e=2.1.2.1.1.4.1.1.6.1.1.8.1.1.10...$$
$$\phi=1.1.1.1.1.1.1.1.1.1.1.1.1.1.1.1...$$
$$171/372=0.2.5.1.2.3$$
