### Is Zero Even or Odd

Is Zero Even or Odd

Many people say it's even, many say it's neither. What is it truly. The def of even is n=2k where k is an integer right. So shouldn't this be even

Re: Is Zero Even or Odd

Another example: if we are not talking about the number zero, but the zero function (which is, a function $f(x)$ that maps to $0$ for every input value $x$), and we ask whether the zero function is an even function or an odd function (if you need to know the definition of even function and odd function, search Wikipedia).  The answer to this question is: it is both.  But this is a completely different question from the question about the number zero.
