Is the number even or odd?
I wanted to create a cusom function to see if a number was even or odd. (weird no such function existed already)
So, IsEvenNumber(number) returns true or false. Nothing weird.
But, the function name is reserved. but there is no such function in the reference. So I tried it, and it works as expected. So now you know, no need to create that function! :) I think it originated from version 9.
