Message 106381 - Python tracker

I don't have a strong feeling about the method of rounding.  My thinking is: If my application is sensitive to how the last microsecond is rounded, then I shouldn't be using a type that only gives me 1-microsecond precision.

(Likewise, if my application is sensitive to how the last binary digital of the floating point mantissa is rounded ... I'm in trouble)

That said, round-to-nearest strikes me as the least-surprising approach.
