Available from 2.8, the ROUND function is equivalent to that in Excel, i.e. rounds a number to a specified number of digits.

Syntax:
ROUND(number, num_digits)
where:
- 'number' is the number that you want to round.
- 'num_digits' is the number of digits to which you want to round the number argument. Default 0 if not specified.

Samples:
ROUND(123.7825, 2) = 123.78
ROUND(123.456, 1) = 123.5
ROUND(123.456, -2) = 100)
