NAME
     values - machine-dependent values

USAGE
     #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 (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, 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

VALUES(5)                DOMAIN/IX SYS5                 VALUES(5)



                    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.
