;;; A "bytevector" is a raw bit string. This module provides procedures to
|
|
;;; manipulate bytevectors and interpret their contents in a number of ways:
|
|
;;; bytevector contents can be accessed as signed or unsigned integer of
|
|
;;; various sizes and endianness, as IEEE-754 floating point numbers, or as
|
|
;;; strings. It is a useful tool to decode binary data.
