0.5 is clearly even, as . 0.5 is neither even (divisible by 2 with a remainder of 0) nor odd (divisible by 2 with a remainder of 1). A number is divisible by other number if their quotient is an integer. Extending this definition to all real numbers, 0.5 / 2 = 0.25 is clearly not an integer, so 0.5 is odd.
