for a number to be even or odd number does it have to be an integer
yes
Yes, for a number to be even or odd, it must be an integer. An integer is a whole number with no fractional or decimal part. Even numbers are integers that are divisible by 2 without leaving a remainder, while odd numbers are integers that are not divisible by 2 without leaving a remainder.
For example, the number 4 is an even integer because it is divisible by 2 without leaving a remainder, while the number 5 is an odd integer because it is not divisible by 2 without leaving a remainder. However, fractions or decimals like 1.5 or 2.75 are not even or odd integers because they are not whole numbers.
