pragma Long_Float (FLOAT_FORMAT);
FLOAT_FORMAT ::= D_Float | G_Float
This pragma is implemented only in the OpenVMS implementation of GNAT.
It allows control over the internal representation chosen for the predefined
type Long_Float and for floating point type representations with
digits specified in the range 7 through 15.
For further details on this pragma, see the
DEC Ada Language Reference Manual, section 3.5.7b. Note that to use
this pragma, the standard runtime libraries must be recompiled. See the
description of the GNAT LIBRARY command in the OpenVMS version
of the GNAT User's Guide for details on the use of this command.
