The Common Lisp algorithm (as translated to Algol 68) does not handle the additional Wren test cases (same as the last two Common Lisp test cases except with extra digits). The more accurate algorithm translated from the Wren sample does handle these cases.
The Common Lisp algorithm (at least, as translated to Algol 68) does not handle the additional Wren test cases. The more accurate algorithm translated from the Wren sample does handle these cases.
