  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 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 (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).

    EXPBASE
           The exponent base.

    DMAXEXP
           The maximum exponent of a double-precision number.

    FMAXEXP
           The maximum exponent of a floating-point number.

    DMINEXP
           The minimum exponent of a double-precision number.

    FMINEXP
           The minimum exponent of a floating-point number.

    MAXFLOAT
           The maximum value of a single-precision floating-point number.

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

    MINFLOAT
           The minimum positive value of a single-precision floating-point
           number.

    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.

    DMAXPOWTWO
           The largest power of two exactly representable as a double-
           precision number.

    LMAXPOWTWO
           The largest power of two exactly representable as a floating-point
           number.

    _IEEE  This value is set to 1 if IEEE standard representation is used.

    _DEXPLEN
           The number of bits for the exponent of a double-precision number.

    _FEXPLEN
           The number of bits for the exponent of a floating-point number.

    _HIDDENBIT
           This value is set to 1 if the high-significance bit of the mantissa
           is implicit.

    LN_MAXDOUBLE
           The natural logarithm of the largest double-precision number.

    LN_MINDOUBLE
           This value represents the natural logarithm of the smallest
           double-precision number.
