Number.round()
From v9.5.2, Number.round() rounds the value of its chained source number argument to the nearest integer. A partial integer over .50 always round up, everything else rounds down.
See round() for a fuller explanation of the logic and possible usage.
See also Number.ceil() and Number.floor().
