Round can be used for decimal fields that have no assigned QFIELDNAME or CFIELDNAME fields. Its purpose is to move decimal places left or right. If you want to move decimal places left, then you have to put there positive numbers, if you want to move decimal places right, then use negative numbers.
Example when you use 0 as round, you’ll get the normal full numbers, the display of the field hasn’t changed.

Now the same program is run with 3 that is inserted into ROUND. You can notice that instead of 2 571,25 you can see 2,5723, so the comma sign was moved left by 3 positions.

Also changed output is visible when you use negative values. This time -5 was used. You can see on image below that instead of 2 571,25 you can see 275 225 000.

In each case the value in the internal table was the same 2 571,25.
