/* mconf.h
|
|||
|
*
|
|||
|
* Common include file for math routines
|
|||
|
*
|
|||
|
*
|
|||
|
*
|
|||
|
* SYNOPSIS:
|
|||
|
*
|
|||
|
* #include "mconf.h"
|
|||
|
*
|
|||
|
*
|
|||
|
*
|
|||
|
* DESCRIPTION:
|
|||
|
*
|
|||
|
* This file contains definitions for error codes that are
|
|||
|
* passed to the common error handling routine mtherr()
|
|||
|
* (which see).
|
|||
|
*
|
|||
|
* The file also includes a conditional assembly definition
|
|||
|
* for the type of computer arithmetic (IEEE, DEC, Motorola
|
|||
|
* IEEE, or UNKnown).
|
|||
|
*
|
|||
|
* For Digital Equipment PDP-11 and VAX computers, certain
|
|||
|
* IBM systems, and others that use numbers with a 56-bit
|
|||
|
* significand, the symbol DEC should be defined. In this
|
|||
|
* mode, most floating point constants are given as arrays
|
|||
|
* of octal integers to eliminate decimal to binary conversion
|
|||
|
* errors that might be introduced by the compiler.
|
|||
|
*
|
|||
|
* For little-endian computers, such as IBM PC, that follow the
|
|||
|
* IEEE Standard for Binary Floating Point Arithmetic (ANSI/IEEE
|
|||
|
* Std 754-1985), the symbol IBMPC should be defined. These
|
|||
|
* numbers have 53-bit significands. In this mode, constants
|
|||
|
* are provided as arrays of hexadecimal 16 bit integers.
|
|||
|
*
|
|||
|
* Big-endian IEEE format is denoted MIEEE. On some RISC
|
|||
|
* systems such as Sun SPARC, double precision constants
|
|||
|
* must be stored on 8-byte address boundaries. Since integer
|
|||
|
* arrays may be aligned differently, the MIEEE configuration
|
|||
|
* may fail on such machines.
|
|||
|
*
|
|||
|
* To accommodate other types of computer arithmetic, all
|
|||
|
* constants are also provided in a normal decimal radix
|
|||
|
* which one can hope are correctly converted to a suitable
|
|||
|
* format by the available C language compiler. To invoke
|
|||
|
* this mode, define the symbol UNK.
|
|||
|
*
|
|||
|
* An important difference among these modes is a predefined
|
|||
|
* set of machine arithmetic constants for each. The numbers
|
|||
|
* MACHEP (the machine roundoff error), MAXNUM (largest number
|
|||
|
* represented), and several other parameters are preset by
|
|||
|
* the configuration symbol. Check the file const.c to
|
|||
|
* ensure that these values are correct for your computer.
|
|||
|
*
|
|||
|
* Configurations NANS, INFINITIES, MINUSZERO, and DENORMAL
|
|||
|
* may fail on many systems. Verify that they are supposed
|
|||
|
* to work on your computer.
