| 20 | * | ||
| 21 | * Common include file for math routines | ||
| 22 | * | ||
| 23 | * | ||
| 24 | * | ||
| 25 | * SYNOPSIS: | ||
| 26 | * | ||
| 27 | * #include "mconf.h" | ||
| 28 | * | ||
| 29 | * | ||
| 30 | * | ||
| 31 | * DESCRIPTION: | ||
| 32 | * | ||
| 33 | * This file contains definitions for error codes that are | ||
| 34 | * passed to the common error handling routine mtherr() | ||
| 35 | * (which see). | ||
| 36 | * | ||
| 37 | * The file also includes a conditional assembly definition | ||
| 38 | * for the type of computer arithmetic (IEEE, DEC, Motorola | ||
| 39 | * IEEE, or UNKnown). | ||
| 40 | * | ||
| 41 | * For Digital Equipment PDP-11 and VAX computers, certain | ||
| 42 | * IBM systems, and others that use numbers with a 56-bit | ||
| 43 | * significand, the symbol DEC should be defined. In this | ||
| 44 | * mode, most floating point constants are given as arrays | ||
| 45 | * of octal integers to eliminate decimal to binary conversion | ||
| 46 | * errors that might be introduced by the compiler. | ||
| 47 | * | ||
| 48 | * For little-endian computers, such as IBM PC, that follow the | ||
| 49 | * IEEE Standard for Binary Floating Point Arithmetic (ANSI/IEEE | ||
| 50 | * Std 754-1985), the symbol IBMPC should be defined. These | ||
| 51 | * numbers have 53-bit significands. In this mode, constants | ||
| 52 | * are provided as arrays of hexadecimal 16 bit integers. | ||
| 53 | * | ||
| 54 | * Big-endian IEEE format is denoted MIEEE. On some RISC | ||
| 55 | * systems such as Sun SPARC, double precision constants | ||
| 56 | * must be stored on 8-byte address boundaries. Since integer | ||
| 57 | * arrays may be aligned differently, the MIEEE configuration | ||
| 58 | * may fail on such machines. | ||
| 59 | * | ||
| 60 | * To accommodate other types of computer arithmetic, all | ||
| 61 | * constants are also provided in a normal decimal radix | ||
| 62 | * which one can hope are correctly converted to a suitable | ||
| 63 | * format by the available C language compiler. To invoke | ||
| 64 | * this mode, define the symbol UNK. | ||
| 65 | * | ||
| 66 | * An important difference among these modes is a predefined | ||
| 67 | * set of machine arithmetic constants for each. The numbers | ||
| 68 | * MACHEP (the machine roundoff error), MAXNUM (largest number | ||
| 69 | * represented), and several other parameters are preset by | ||
| 70 | * the configuration symbol. Check the file const.c to | ||
| 71 | * ensure that these values are correct for your computer. | ||
| 72 | * | ||
| 73 | * Configurations NANS, INFINITIES, MINUSZERO, and DENORMAL | ||
| 74 | * may fail on many systems. Verify that they are supposed | ||
| 75 | * to work on your computer. | ||
