- procedure:
**unsigned-integer->bit-string***length integer*¶ Both

`length`and`integer`must be exact non-negative integers. Converts`integer`into a newly allocated bit string of`length`bits. Signals an error of type`condition-type:bad-range-argument`

if`integer`is too large to be represented in`length`bits.

- procedure:
**signed-integer->bit-string***length integer*¶ `Length`must be an exact non-negative integer, and`integer`may be any exact integer. Converts`integer`into a newly allocated bit string of`length`bits, using two’s complement encoding for negative numbers. Signals an error of type`condition-type:bad-range-argument`

if`integer`is too large to be represented in`length`bits.

- procedure:
**bit-string->unsigned-integer***bit-string*¶ - procedure:
**bit-string->signed-integer***bit-string*¶ Converts

`bit-string`into an exact integer.`bit-string->signed-integer`

regards`bit-string`as a two’s complement representation of a signed integer, and produces an integer of like sign and absolute value.`bit-string->unsigned-integer`

regards`bit-string`as an unsigned quantity and converts to an integer accordingly.
