There is a specific rule(Banker's Rule I think) for rounding of numbers that end in 5. The rule is that we add 1 to the preceding digit of it's odd but keep it as it is if it's even. It's always keeping it even.(adsbygoogle = window.adsbygoogle || []).push({});

Why is this rule applied? I read something like it is done to prevent biased rounding off our something.
