The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/13/functions-math.html 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.
