     Computes absolute value

SYNOPSIS
     ABS ([A=]a)
     DABS ([A=]a)
     QABS ([A=]a)
     IABS ([A=]a)
     IIABS ([A=]a)
     JIABS ([A=]a)
     KIABS ([A=]a)

STANDARDS
     Fortran

     Fortran extensions:  QABS, IIABS, JIABS, KIABS, CQABS, CDABS

DESCRIPTION
     ABS is the generic function name; the others are specifics.  These are
     elemental intrinsic functions.  They accept the following arguments:

     x         Must be a numeric data type (real, complex, or integer) of
               any supported kind type.  See the RETURN VALUES section for
               more information on input data types and return values.

     These functions evaluate as follows:  y = |x|, except for CABS and
     CDABS, which evaluate the following:

          y = |(xr2 + xi2)1/2|

NOTES
     The ABS, IABS, DABS, and CABS intrinsic function names can be passed
     as arguments; the others cannot.

RETURN VALUES
     ABS returns the absolute value of its argument.  The data type of the
     result is the same as the data type of a except that if input argument
     a is type complex, the result is type real.

     DABS returns the double-precision absolute value of its
     double-precision argument.

     QABS returns the quad-precision absolute value of its quad-precision
     argument.

     IABS returns the integer absolute value of its integer argument.

     IIABS returns the integer (KIND=2) absolute value of its integer
     (KIND=2) argument.

     JIABS returns the integer (KIND=4) absolute value of its integer
     (KIND=4) argument.

     KIABS returns the integer (KIND=8) absolute value of its integer
     (KIND=8) argument.

     CABS returns the absolute value of its single-precision complex
     argument as a single-precision real number.

     CDABS returns the absolute value of its complex double-precision
     argument as a double-precision real number.

     CQABS returns the absolute value of its complex quad-precision
     argument as a quad-precision real number.

     The terms single precision, double precision, and quad precision
     differ depending on your platform.  For platform-specific information,
     see the TERMINOLOGY section of the INTRO_INTRIN(3I) man page.
