+ *
+ * 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.
