SYNOPSIS

DESCRIPTION

This file contains a set of manifest constants, conditionally defined for particular processor architectures.

The model assumed for integers is binary representation (one's or two's complement), where the sign is represented by the value of the high-order bit.

BITS(type)

The number of bits in a specified type (for instance, int).

HIBITS

The value of a short integer with only the high-order bit set (in most implementations, 0x8000).

HIBITL

The value of a long integer with only the high-order bit set (in most implementations, 0x80000000).

HIBITI

The value of a regular integer with only the high-order bit set (usually the same as HIBITS or HIBITL).

MAXSHORT

The maximum value of a signed short integer (in most implementations, 0x7FFF == 32767).

MAXLONG

The maximum value of a signed long integer (in most implementations, 0x7FFFFFFF == 2147483647).

MAXINT

The maximum value of a signed regular integer (usually the same as MAXSHORT or MAXLONG).

MAXFLOAT

LN_MAXFLOAT

The maximum value of a single-precision floating-point number, and its natural logarithm.

MAXDOUBLE

LN_MAXDOUBLE

The maximum value of a double-precision floating-point number, and its natural logarithm.

MINFLOAT

LN_MINFLOAT

The minimum positive value of a single-precision floating-point number, and its natural logarithm.

MINDOUBLE

LN_MINDOUBLE

The minimum positive value of a double-precision floating-point number, and its natural logarithm.

FSIGNIF

The number of significant bits in the mantissa of a single-precision floating-point number.

DSIGNIF

The number of significant bits in the mantissa of a double-precision floating-point number.
