values - machine-dependent values
SYNOPSIS
#include <values.h>
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 (e.g., 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.
