Yes and no. No: bankers round to the nearest even digit. Yes:
100.105 becomes 100.10. And 100.115 becomes 100.12.

And that is exactly what round-half-to-even does (like stated in my
first post in this thread ;) See
http://www.w3.org/TR/xpath-functions/#func-round-half-to-even, and
consider this quote:

"This function is typically used in financial applications where the
argument is of type xs:decimal. For arguments of type xs:float and
xs:double the results may be counterintuitive. For example, consider
round-half-to-even(xs:float(150.0150), 2)."
