> some of which will is due to not emulating a weird IEEE floating point rule about rounding numbers of the form N.5 to the even number instead of up like everyone is taught in school. Round-to-even (also known as banker's rounding, because it's used in finance too) isn't weird at all. It minimizes rounding error, especially on repeated calculations. The rounding rule that everyone learns in elementary school is bad and results in systematically biased computations. We can and should do better than that flawed approach.
