3 

The minimalist value of pi (unless you need a far better approximation to ensuring that someone lands safely on a distant planet, or that a computer system is in good working conditions).

For most practical purposes involving the constant π, you’d do fine with the quick-and-dirty value of 3.

An anime face that resembles a kitten's face, it is often used to indicate sarcasm, 'I didn't do it!' kind of thing, or seeing something cute. Some anime characters, like Konata from Lucky Star, has the kitty face. It has a colon, ended with the number 3.

Person 1: This image is so cute! :3

Person 2: I didn't post it! :3

The ultimate number, this number cannot be matched. It is the very workings of this universe, the foundation of life, the opening to eternal peace, joy and tranquility.

"What's your favourite number?"

"3"

"Good, you will succeed in life"

You meant to just hit the Entre/Return key typing in, "3," but accidentally hit the, "\," key with it, resulting in, "3\."

the fact that there was a definition for 3\ made you curious
