DDBBLLEE: Fortran 90 standard
DDFFLLOOAATT is a compiler extension to Fortran 90.
DDEESSCCRRIIPPTTIIOONN
These functions convert specified types to double precision type.
DDBBLLEE and DDFFLLOOAATT are elemental functions for the CF90 compiler.
_a_r_g or _a can be of type complex, integer, real, or double precision.

DDBBLLEE:
Real, and double precision:

|_x|< infinity (infinity is approximately 10 )
On UNICOS/mk systems and on CRAY T90 systems that support IEEE
arithmetic:

infinity is approximately 10
Complex:
|_x | < infinity; for complex arguments, _x =_x + _i_x .
_r _r _i
Integer:

DDFFLLOOAATT:
63
|_x| < 2

DDBBLLEE returns the double-precision equivalent of its complex, integer,
real, or double-precision argument.
DDFFLLOOAATT returns the double-precision floating-point equivalent of its
integer argument.
