Fwd: A question about the rat command

You can convert objects from rational (CRE) form to general representation
using totaldisrep.

        is( ident(2) = rat( ident(2 ) ) ) => false

but

        is( ident(2) = totaldisrep(  rat( ident(2) ) ) ) => true

You might also want to use "equal" rather than "=" for comparison here.
Unfortunately, there seems to be a bug in 5.9.3/GCL/Windows:

       is( equal( ident(2), rat( ident(2 ) ) ) )  => internal error

           -s
