- *
- * 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 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.
- *
- * 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, the symbol UNK is defined.
- *
- * 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.
