NAME
     DBLE - Converts to double-precision real

SYNOPSIS
     DBLE ([A=]a)

STANDARDS
     Fortran

DESCRIPTION
     This intrinsic function converts the specified type to double
     precision.  This is an elemental intrinsic functions.  It accepts the
     following arguments:

     a         Must be type integer, real, or complex.

               If a is of type complex, an approximation of the real part
               of a is returned.  As much precision as possible is
               retained.

               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.

NOTES
     The name of this intrinsic function cannot be passed as arguments.

RETURN VALUES
     DBLE returns the double-precision equivalent of its argument.
