unit:BIT

In information theory, a bit is the amount of information that, on average, can be stored in a discrete bit. It is thus the amount of information carried by a choice between two equally likely outcomes. One bit corresponds to about 0.693 nats (ln(2)), or 0.301 hartleys (log10(2)).

Note: This unit represents the information-entropy bit (conversionMultiplier = ln(2)), not the count-of-binary-digits bit used in phrases such as "a 64-bit integer". Its extended dimension vector has N=0, reflecting the continuous information-theoretic interpretation. A separate counting unit (N=1) for the binary-digit usage may be defined in a future version.
