You've got it completely backwards. Floating point is in fact the best possible representation for multiplying two numbers with wildly different scales (obviously, all you have to do is add the exponents). Adding two numbers with different scaling factors is a problem, but an extremely minor one (truncation error).
The biggest error comes from subtracting two numbers that are very close together, since there aren't many significant figures to go on to rescale the result. And not a single one of these can possibly explain the pathologically buggy behaviour of Calculator.app.
