NAME
values - machine-dependent values
USAGE
#include <values.h>
DESCRIPTION
This file contains a set of manifest constants, condition-
ally 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 imple-
mentations, 0x8000).
HIBITL The value of a long integer with only
the high-order bit set (in most imple-
mentations, 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.
