NAME
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.
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.
