My understand is no, not if you're using IEEE floating point.
Yes, that would explain it. I assumed that Python automatically
switched from hardware floating point to multi-precision floating
point so that the user is guaranteed to always get correctly rounded
results for +, -, *, and /, like Flaming Thunder gives. Correct
rounding and accurate results are fairly crucial to mathematical and
scientific programming, in my opinion.
Who says that rounding on base 10 is more correct than rounding on base 2?
And in scientific programming, speed matters - which is why e.g. the
cell-processor shall grow a double-precision float ALU. And generally
supercomputers use floats, not arbitrary precision BCD or even rationals.
