Does anyone know of a package supporting double-length integer
(and ideally fixed point) types ?
[ i.e. to provide support for a 2n-bit integer/fixed types using a compiler
which uses n-bits for its largest integer/fixed types ]
I'm looking at a couple of the arbitrary-size support packages, but
I'd be interested to know if there are any more specific alternatives.
TIA

With a package providing arbitrary-size package you can define a fixed-size
subtype :-) E.g.
NB_Blocs_maximal: constant:= 4;
SUBTYPE ENTIER IS Multi_precision_integers.multi_int( NB_Blocs_maximal );
Some links for multi-precision @ http://members.xoom.com/gnatlist/
