NAME
     DPROD, QPROD - Computes double-precision or quad-precision product of
     two real numbers

SYNOPSIS
     DPROD ([X=]x,[Y=]y)
     QPROD ([X=]x,[Y=]y)

IMPLEMENTATION
     UNICOS, UNICOS/mk, IRIX systems

     CF90, MIPSpro 7 Fortran 90, MIPSpro Fortran 77

STANDARDS
     Fortran

     Fortran extension:  QPROD

DESCRIPTION
     DPROD returns the double-precision real product of its two real
     arguments.  QPROD returns the quad-precision real product of its two
     real arguments.  These are elemental functions.  They accept the
     following arguments:

     x         Must be of type single-precision real or double-precision
               real.  See the RETURN VALUES section for information on
               input data types and return values.

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

     y         Must be of the same type and kind type as x.

     These functions evaluate y = x * y.

RETURN VALUES
     DPROD returns the double-precision real product of two real arguments.

     QPROD returns the quad-precision real product of two real arguments.

NOTES
     The name of this intrinsic can be passed as an argument.

EXAMPLES
     The following program calls DPROD to compute the double-precision
     product of the two real numbers 5.0 and 6.0:

          PROGRAM DOUBT
          REAL X,Y
          DOUBLE PRECISION Z
          X=5.0
          Y=6.0
          Z=DPROD(X,Y)
          PRINT *, Z
          STOP
          END

     The preceding program gives Z to be the double-precision number 30.0
     (or in Fortran, 30.D0).
