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 (for example,
                         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.
