ssed blocks of binary data, in short, <i>blobs</i>. The SRFI provides access primitives for fixed-length integers of arbitrary size, with specified endianness, and a choice of unsigned and two's complement representations.</p><h1>Rationale</h1><p>Many applications must deal with blocks of binary data by accessing them in various ways---extracting signed or unsigned numbers of various sizes.  Such an application can use octet vectors as in <a href="http://srfi.schemers.org/srfi-66/">SRFI 66</a> or any of the
