The Split command breaks the input number into a list of sbits bit length (default is 1) numbers, least significant bits first.

The most common usage of this command would be for conversion of a number into its base-2 digits, but it could also be used, for example, to convert a number to octal or hex (see convert/octal or convert/hex).

The option bits=n tells Split how many bits to consider in the split. Any bits in a higher position are simply ignored.

The reverse operation, converting the digits to a number, is accomplished using the Join command.
