That's slightly dangerous, because it doesn't work with all possible number formats. An entry of 0e0 (which is a valid zero) causes the comparison to disregard all non-zeros after it, as does two 0.0s (though it warns).

Of course if one knows that the entries are always exactly 0 or 1, it's quite an elegant solution.
