infinint left shift operation

Hi,

When using the "operator <<=" I'm getting weird results:


[ libdarc code ]

extern "C" void dar_infinint_shiftl( dar_infinint** a, dar_infinint* b )
{
	infinint* ar = (infinint*)*a;
	infinint* br = (infinint*)b;
	*ar <<= *br;
}

extern "C" void dar_infinint_shiftli( dar_infinint** a, int bit )
{
	infinint* ar = (infinint*)*a;
	*ar <<= bit;
	//*a = (dar_infinint*)ar;
}


I call the equivalent of dar_infinint_shiftl(4, 1), getting the
following results:

a original = 4
b original = 1
value = 2048

Both operators return incorrect values.


I also get:

a original = 1000
b original = 1
value = 512000


Right shift seems to work okay.


Thanks.
