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.

      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.
