vX: Number which is rounded-up to the next even number (i.e. 2, 4, 6, -2, -4, -6, etc.). Function returns Null if vX is Null or cannot be fixed up to a number.
Note: Similar to calling the Ceiling function with a precision of 2 (two), except that if vX is already an even number, this function returns the next even number.
Note: Zero is considered an even number, as are all negative numbers divisible by two.
