Is pi a number?

But pi is an irrational number, meaning that its decimal form neither ends (like 1/4 = 0.25) nor becomes repetitive (like 1/6 = 0.166666...). (To only 18 decimal places, pi is 3.141592653589793238.) Hence, it is useful to have shorthand for this ratio of circumference to diameter.

Is infinity odd or even?

Also, this concept of infinity has one of the most successful parity concepts, since one maintains the even/odd pattern into the transfinite. The smallest infinity ω is even, ω+1 is odd, ω+2 is even and so on. Every limit ordinal is even, and then it repeats even/odd up to the next limit ordinal.
