NAME    [Toc]    [Back]

     values - machine-dependent	values

SYNOPSIS    [Toc]    [Back]

     #include <values.h>

DESCRIPTION    [Toc]    [Back]

     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 highorder
 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 singleprecision
 floating-point number, and	its
				   natural logarithm.

     MINDOUBLE,	LN_MINDOUBLE	   The minimum positive	value of a doubleprecision
 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.
