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.

       HIBITL        The value of a long integer with only the high-order
                     bit set.

       HIBITI        The value of a regular integer with only the high-order
                     bit set.

       MAXSHORT      The maximum value of a signed short integer.

       MAXLONG       The maximum value of a signed long integer.

       MAXINT        The maximum value of a signed regular integer.

       MAXFLOAT, LNMAXFLOAT
                     The maximum value of a single-precision floating-point
                     number, and its natural logarithm.

       MAXDOUBLE, LNMAXDOUBLE
                     The maximum value of a double-precision floating-point
                     number, and its natural logarithm.

       MINFLOAT, LNMINFLOAT
                     The minimum positive value of a single-precision
                     floating-point number, and its natural logarithm.

       MINDOUBLE, LNMINDOUBLE
                     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.
