Question

What does pie equal?

Answer 1

Pie is pie, as in apple, cherry, chocolate, etc.,  You meant "pi," whose symbol is π.

pi, or π, is usually approximated by 3.14; sometimes I use 3.14159.  However, pi, or π, is irrational, not expressable as the ratio of two integers, and thus the string of digits never stops.

Answer 2

3.14 although technically pi does not end after the 4.
