====== Balanced base 27 =====

Balanced bace-27 (BB27) is used in vulpithecine computing in a similar manner to hexadecimal. Yinrih computers are based on [[balanced ternary]] instead of binary, where each digit can represent -1 (written T), 0, or 1. Balanced base-27 uses 27 digits which can represent the decimal range -13 to +13. The Yinrih Internetworking Protocol (YIP) uses BB27 to represent YIP addresses.



The table below is a human-friendly version of what yinrih actually use. Yinrih numerals are written with the highest-order digit to the right, since yinrih write right to left.



For everyday use, yinrih use either base-12 or base-24.
