Round to nearest Fields: AwayFromZero ToEven A round-to-nearest operation takes an original number with an implicit or specified precision; examines the next digit, which is at that precision plus one; and returns the nearest number with the same precision as the original number. For positive nu...
The documentation for the built-inround()function says that it rounds to the nearest value, rounding ties away from zero. Since the decimal fraction 2.675 is exactly halfway between 2.67 and 2.68, you might expect the result here to be (a binary approximation to) 2.68. It’s not, because...

If you want to keep all of the digits after the decimal point, you can use the ROUND() function with the “round to nearest” flag. For example, round(12.345, True) will return 12.34 because it rounds the number up to the nearest .01 value. ...
