/*
* $Id$
*
* MACROS for rapid conversion between HOST data formats and those used
* by the IOCs (NETWORK).
*
* Author: J. Hill
*
* The conversion routines are used in both ca lib
* and the IOC ca server (base/rsrv).
* The latter, however, cannot include os_depen.h so
* I extracted the conversion specific code from there
* and put it in this "now stand alone" net_convert.h
* 8-22-96 -kuk-
*
*
* joh 09-13-90 force MIT sign to zero if exponent is zero
* to prevent a reseved operand fault.
*
* joh 03-16-94 Added double fp
* joh 11-02-94 Moved all fp cvrt to functions in
* convert.c
*
