Description:

The 'round' mathematical function documentation doesn't specify its rounding
strategy. If this would be documented then users can rely on its rounding
behavior. For double precision the rounding probably depends on your
platform. For numeric the function seems to round to nearest with ties going
away from zero (sometimes referred to as "round half up). 6.5 -> 7.0 and
-6.5 -> -7.0.
