Round() returns the result of rounding x up or down to the nearest multiple of step [+ offset]. The default value of offset is 0. The default value of step is 1.
If x is exactly in the middle of an interval, it is rounded upwards.
Syntax:
Round(x[, step[, offset]])
Return data type: numeric
If you are rounding a floating point number you may experience results that are erroneous. These mostly insignificant rounding errors are due to that floating point numbers are represented by a finite number of binary digits. That results in QlikView calculating with a number that is already rounded. If it is critical to have correct rounding, a workaround is to multiply the numbers to convert them to integers.
Examples and results:
Examples
Results
Round( 3.8 )
Returns 4
Round( 3.8, 4 )
Returns 4
Round( 2.5 )
Returns 3. Rounded up because 2.5 is exactly half of the default step interval.
Round( 2, 4 )
Returns 4. Rounded up because 2 is exactly half of the step interval of 4.
Round( 2, 6 )
Returns 0. Rounded down because 2 is less than half of the step interval of 6.
