- -- 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.
