-- Abstract     : This package is a floating mantissa definition
----------------: of a binary FLOAT.  It was first used on the 
----------------: DEC-10 and the VAX but should work for any 
----------------: since the parameters are obtained by initial-
----------------: izing on the actual hardware.  Otherwise the 
----------------: parameters could be set in the spec if known.
----------------: This is a preliminary package that defines the
----------------: properties of the particular floating point 
----------------: type for which we generate the math routines.
----------------: 
----------------: The constants are those required by the routines
----------------: described in "Software Manual for the Elementary
----------------: Functions" W. Cody and W. Waite, Pretice-Hall
----------------: 1980.  Actually most are needed only for the
----------------: test programs rather than the functions them-
----------------: selves.  Most of these could be in the form of 
----------------: attributes if all the floating types to be 
----------------: considered were those built into the compiler, 
----------------: but we also want to be able to support user 
----------------: defined types such as software floating types
----------------: of greater precision than the hardware affords,
----------------: or types defined on one machine to simulate
----------------: another. 
----------------: 
----------------: This tool was developed as a precursor for 
----------------: the WMCCS Information System (WIS).  An
----------------: executable version of the tool has been 
----------------: demonstrated.  This source code has sub-
----------------: sequently been recompiled but has not under-
----------------: gone extensive testing.
