SPACING(3I)					       Last changed: 1-6-98

NAME
     SPACING - Returns the absolute spacing of real model numbers near the
     argument value

SYNOPSIS
     SPACING ([X=]x)

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     Fortran 90

DESCRIPTION
     The SPACING intrinsic function returns the absolute spacing of real
     model numbers near the argument value.  It accepts the following
     argument:

     x	  Must be of type real

     SPACING is an elemental function.	The name of this intrinsic cannot
     be passed as an argument.

NOTES
     This routine is implemented on CRAY T90 systems that support IEEE
     arithmetic by calls to scalar-only library routines.

RETURN VALUES
     The result type and type parameter are the same as x.
			       e-p
     The result has the value b	  , where b, e, and p are as defined in the
     real number model, provided this result is within range.  If not, the
     result is the same as that of TINY (x).  For more information on the
     real number model, see the MODELS(3I) man page.

EXAMPLES
     Example 1:	 A CRAY C90 system returns the following values for the
     SPACING intrinsic function:

	  SPACING(3.0)= 2.8421709430404E-14
	  SPACING(3.0_4)= 2.384185791015625E-7
	  SPACING(3.0_8)= 2.8421709430404E-14
	  SPACING(3.0_16)= 1.009741958682895E-28

     The first is default type real, and the others are defined.

     Example 2:	 An IRIX system returns the following values for the
     SPACING intrinsic function:

	  SPACING(3.0)= 2.384185791E-7
	  SPACING(3.0_4)= 2.384185791E-7
	  SPACING(3.0_8)= 4.44089209850062616E-16
	  SPACING(3.0_16)= 2.46519032881566189191165176650870697E-32

     The first is default type real, and the others are defined.

     Example 3:	 A UNICOS/mk system returns the following values for the
     SPACING intrinsic function:

	  SPACING(3.0)= 4.44089209850062616E-16
	  SPACING(3.0_4)= 2.384185791015625E-7
	  SPACING(3.0_8)= 4.44089209850062616E-16
	  SPACING(3.0_16)= 4.44089209850062616E-16

     Example 4:	 A CRAY T90 system that supports IEEE floating-point
     arithmetic returns the following values for the SPACING intrinsic
     function:

	  SPACING(3.0)= 4.44089209850062616E-16
	  SPACING(3.0_4)= 4.44089209850062616E-16
	  SPACING(3.0_8)= 4.44089209850062616E-16
	  SPACING(3.0_16)= 3.85185988877447171E-34

     Note that there is no KIND=4 value and that default is KIND=8.
