Detailed Description

Defines the 'base' SRM types.

Author:: Bill Horan (SAIC)

CHANGE THIS FILE, IF NEEDED, TO MATCH YOUR MACHINE!

This file:

defines whether your machine is Big or Little Endian (THIS MAY NEED TO BE CHANGED TO MATCH YOUR MACHINE)

defines the 'base' SRM types: (THESE MAY NEED TO BE CHANGED TO MATCH YOUR MACHINE) signed 8, 16, and 32 bit integers, unsigned 8, 16, and 32 bit integers, 32 and 64 bit floating point numbers

defines a boolean type (SRM_Boolean), along with true and false values (SRM_TRUE and SRM_FALSE)

defines constants that signify Positive and Negative Infinity within SRM (the constants used are the appropriate IEEE values)

defines constants that signify min and max values for the 'base' SRM numeric types

YOU WILL NEED TO CHANGE THIS FILE:

IF YOUR MACHINE IS NOT BIG ENDIAN
IF YOUR MACHINE USES INTs OR FLOATs WITH DIFFERENT SIZES THAN THOSE USED IN THE PROVIDED DEFINITIONS

By 'default', this header file is designed for a Big Endian machine with a 32 bit integer. The 'default' type definitions are:

(SRM Base Type -- machine specific type)

signed 8 bit integer -- signed char
signed 16 bit integer -- short
signed 32 bit integer -- int
unsigned 8 bit integer -- unsigned char
unsigned 16 bit integer -- unsigned short
unsigned 32 bit integer -- unsigned int
positive 8 bit integer -- unsigned char
positive 16 bit integer -- unsigned short
positive 32 bit integer -- unsigned int
32 bit float -- float
64 bit float -- double

IF THESE "machine specific" TYPES ARE NOT CORRECT FOR YOUR MACHINE, THEN CHANGE THE DEFINITIONS TO THE APPROPRIATE MACHINE SPECIFIC TYPES USED IN THE "typedef" STATEMENTS TO BE CORRECT FOR YOUR MACHINE.

For example, if on your machine an int is 16 bits, and a long int is 32 bits, then you would probably change the integer declarations to read as follows:

typedef long int SRM_Integer;

typedef unsigned long SRM_Integer_Unsigned;

typedef unsigned long SRM_Integer_Positive;

IF YOUR MACHINE IS NOT DEFINED AS A LITTLE ENDIAN MACHINE, THEN ADD THE APPROPRIATE #defined() TO THE LINE THAT READS

"#if defined(CPUARCH_i386)..."

This file is the only SRM file that should need to be changed due to machine (platform/OS) differences.

Define Documentation

#define SRM_EQUAL ( a,
b,
delta )

Value:
( ((a) == (b)) || \ ((a)-(delta) < (b) && (a)+(delta) > (b)) )
MACRO: SRM_EQUAL
A convenient macro to test whether two floating point numbers are within delta of each other (to avoid the classic problem of using == to compare equality among floating point numbers)
Definition at line 281 of file srm_stds.h.

#define SRM_INTEGER_MAX 2147483647

Used to define the max integer value.
Definition at line 208 of file srm_stds.h.

#define SRM_INTEGER_MIN (-2147483647-1)

Used to define the min integer value.
Definition at line 212 of file srm_stds.h.

#define SRM_INTEGER_POSITIVE_MAX 4294967295U

Used to define the max integer positive value.
Definition at line 224 of file srm_stds.h.

#define SRM_INTEGER_POSITIVE_MIN 1

Used to define the min integer positive value.

#define SRM_INTEGER_UNSIGNED_MAX 4294967295U

Used to define the max integer unsigned value.
Definition at line 216 of file srm_stds.h.

#define SRM_INTEGER_UNSIGNED_MIN 0

Used to define the min integer unsigned value.
Definition at line 220 of file srm_stds.h.

#define SRM_INTERIM_VERSION '\0'

Specifies the interim version letter of the release of the SRM implementation. This shall be '' for none; between 'a' and 'z' inclusive, for an unofficial interim version.
Definition at line 272 of file srm_stds.h.

#define SRM_MAJOR_VERSION ((SRM_Integer_Positive)4)

Specifies the major version number of the release of the SRM implementation.
Definition at line 259 of file srm_stds.h.

#define SRM_MINOR_VERSION ((SRM_Integer_Unsigned)1)

Specifies the minor version number of the release of the SRM implementation.
Definition at line 265 of file srm_stds.h.

#define SRM_NEGATIVE_INFINITY (*(SRM_Long_Float *)__srm_64_neg_infinity)

The constant negative 64 infinity value.
Definition at line 253 of file srm_stds.h.

#define SRM_POSITIVE_INFINITY (*(SRM_Long_Float *)__srm_64_pos_infinity)

The constant positive 64 infinity value.
Definition at line 249 of file srm_stds.h.
