Early Bronze Age recollections:

I was taught to go just one decimal beyond the digit to be rounded. Four or
less rounds down, 5 or more rounds up.

We were specifically taught that it doesn't matter what's beyond that first
digit. Whether the digit being rounded is odd or even was never mentioned as
being significant.
