Is $\pi$ even or odd?

Question

This question is a question in my textbook, and I cannot stop thinking about it. The question: Is $\pi$ even or odd? I don't know if even or odd is defined for decimals or for irrational numbers, or if it is, how to find whether $\pi$ is even or odd. Can somebody help?

Answer 1

Even numbers and odd numbers are defined only for integers, as an integer is even when it is of form $2k$, where $k$ is an integer, an integer is odd when it is of form $2p+1$, where $p$ is an integer. But $\pi$ is irrational(in fact transcedental). So there is no way of this.
