base-dependent digit: representing exactly one half of one more than the maximum possible single-digit number expressible in the relevant number base
Some pathologies are possible. For a non-balanced, fixed, positive, arithmetic base (such as standard binary, decimal, hexadecimal), this is half of the base (respectively: '1', '5', '8') - in other words, this word in this case (and if the base is even) is equivalent to "vei (vei) pano (ju'u ny ve'o) fe'i re ve'o boi'ai"; moreover, if the base is odd, then the result (the meaning of this word) is undefined generically at the current moment and is context- or convention-dependent. In measuring time of day, this word can mean six, twelve, thirty, etc., depending on context (and ignoring leap time-units). For the base-dependent digit for the maximum possible single-digit number expressible in the relevant number base, see vu'ai.
