NAME
     DBLE, DFLOAT - Converts to type double precision

SYNOPSIS
     DBLE ([A=]a)

     UNICOS, UNICOS/mk, and IRIX systems:
     DFLOAT ([A=]a)

IMPLEMENTATION
     UNICOS, UNICOS/mk, and IRIX systems

STANDARDS
     DBLE:  Fortran 90 standard
     DFLOAT is a compiler extension to Fortran 90.

DESCRIPTION
     These functions convert specified types to double precision type.

     DBLE and DFLOAT are elemental functions for the CF90 compiler.

     arg or a can be of type complex, integer, real, or double precision.

   Argument Range
     DBLE:

     Real, and double precision:
                                                     2450
          |x|< infinity (infinity is approximately 10    )

          On UNICOS/mk systems and on CRAY T90 systems that support IEEE
          arithmetic:
                                           308
               infinity is approximately 10

     Complex:

          |x | < infinity; for complex arguments, x =x  + ix .
            r                                         r     i
     Integer:
                 63
          |x| < 2

     DFLOAT:
                 63
          |x| < 2

NOTES
     The name of this intrinsic cannot be passed as an argument.

RETURN VALUES
     DBLE returns the double-precision equivalent of its complex, integer,
     real, or double-precision argument.

     DFLOAT returns the double-precision floating-point equivalent of its
     integer argument.
