Does odd/even have much meaning with floating point numbers,

real or otherwise?

Being even means it can be divided by two without any remainder,

but with any king of floating point, remainder doesn't have much

meaning. ie. is 3.4 or 3.5 odd or even? What are the reaminders?

Is PI odd or even?

The only way to decide is to convert them to integers, and then

decide, but then you are working with a different set of numbers.
