round

double

Return Type: long

Round to the nearest long, choosing the next greater integer when exactly in between, and throwing an exception if out of range. If the argument is NaN, the result is 0L. If the argument is out of range, the result is either MaxLong / MinLong, depending on the sign.

x = round(1.6)
