     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 (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,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

     values(5)                                               values(5)



               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.
