Other rounding standards

Some disciplines or institutions accept issued standards or directives for rounding.

editU.S. Acclimate Observations

In a guideline issued in mid-1966,18 the U.S. Office of the Federal Coordinator for Meteorology bent that acclimate abstracts should be angled to the abutting annular number, with the "round bisected up" tie-breaking rule. For example, 1.5 angled to accumulation should become 2, and −1.5 should become −1. Prior to that date, the tie-breaking aphorism was "round bisected abroad from zero".

editNegative aught in meteorology

Some meteorologists may address "−0" to announce a temperature amid 0.0 and −0.5 degrees (exclusive) that was angled to integer. This characters is acclimated if the abrogating assurance is advised important, no amount how baby is the magnitude; for example, if rounding temperatures in the Celsius scale, area beneath aught indicates freezing.
