   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, 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.

   values(5)                                                         values(5)


         DSIGNIF       The number of significant bits in the mantissa of a
                       double-precision floating-point number.
