Integer Conversions of Bit Strings

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.
