Unambiguously state the rounding direction of rounding functions
The descriptions of many of the rounding functions use wording such as "round up" or "round down". These terms are ambiguous for negative numbers. Please instead use unambiguous wording such as "round away from 0", "round towards 0", "round towards −∞", and "round towards ∞". Below is a list of rounding functions whose description does not make the rounding direction clear.
