RoundingMode::HALF_EVEN

Rounds towards the "nearest neighbor" unless both neighbors are equidistant, in which case rounds towards the even neighbor.

Behaves as for HALF_UP if the digit to the left of the discarded fraction is odd; behaves as for HALF_DOWN if it's even.

Note that this is the rounding mode that statistically minimizes cumulative error when applied repeatedly over a sequence of calculations. It is sometimes known as "Banker's rounding", and is chiefly used in the USA.
