...C encoding scheme was devised as an efficient of encoding the binary-coded decimal code on punched cards into 6-bits. Today, EBCDIC is still used in IBM mainf ! Binary !! Octal !! Decimal !! Hexadecimal !! Mnemonic !! Name

...4 bits was a logical choice for many calculators that used [[binary coded decimal|BDC]] numbers representation.

...n use any other numerical representation such as [[binary-coded decimal]]. Binary adders are typically simpler to design when compared to a BCD adder where r Parallel prefix adders are a class of highly-efficient binary adders. Several parallel-prefix adder topologies have been developed that e

Many counter circuits are "binary counters" -- it counts in natural [[binary]] -- 0, 1, 10, 11, 100, ... up to an all-ones state, and then roll over bac The decade counters, also called "binary coded decimal" counters, use the same sequence, but each block of 4 bits only counts up t
