- For example, 1/2, 3/2, and 3/8 are dyadic rationals, but 1/3 is not.
- These numbers are important in computer science because they are the only ones with finite binary representations.
- Dyadic rationals also have applications in weights and measures, musical time signatures, and early mathematics education.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Dyadic rational article was read about 16,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 75: each hit it takes is cut by 30 %.
How to get Dyadic rational
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
