For lip-rounding in phonetics, see Labialisation. For other uses of "rounding", see Round. Rounding is the process of reducing the number of significant digits in a number. The result of rounding is a "shorter" number having fewer non-zero digits yet similar in magnitude. The result is less precise but easier to use.
