evendigit

An evendigit number is a positive integer that contains only even digits. These digits are 0, 2, 4, 6, and 8. Evendigit numbers are a subset of the broader category of numbers that can be classified based on their digits. They are often studied in number theory and recreational mathematics. The smallest evendigit number is 0, and the next few are 2, 4, 6, 8, 20, 22, 24, and so on. Evendigit numbers can be of any length, and they do not have any specific properties that make them unique in terms of mathematical operations. However, they can be used in various puzzles and problems, such as finding the nth evendigit number or determining the number of evendigit numbers within a given range. In some contexts, evendigit numbers are also referred to as "even-digit numbers" or "numbers with only even digits."
