da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chinThese routines convert integral constants between internal and
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chinexternal representations.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chinThey are used to handle binary data generated by foreign programs.
da2e3ebdc1edfbc5028edf1354e7dd2fa69a7968chinNew binary data representations should use the compact canonical form
