Ya the above answer is right. But are you actually in need of these silly answers??

Because you just ask and ask.

Pedantic I know, but Pi is an irrational number, meaning you can never express it as a fraction (or ratio of integers) precisely. Nor can you express it as a decimal precisely: 3.142 is an approximation - yes it's accurate enough for most purposes but it's not exactly that. The digits can go on forever, so we use instead we the symbol for pi to represent it.
