Hardware stack on 80x87 is indeed 8 levels deep. However many floating point
libraries trap stck overflow/underflow exceptions and virtualize hardware
stack to provide many more levels.
Last time I've checked Microsoft floating point library, the stack overflowed
at 32 levels.
If your deeply nested expressions are rare enough, you may be satisfied
with overall performance of your code without doing anything clever to
reorganize expressions into shallower form.
