NAME
     values - machine-dependent values

SYNOPSIS
     #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.

     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 loga-
                   rithm.

     MAXDOUBLE, LN_MAXDOUBLE
                   The maximum value of a double-precision
                   floating-point number, and its natural loga-
                   rithm.

     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.
