    Can anyone please help me how to set the precision for the Decimal Values. In my Line Edit i can enter any number of integer values & i want to set the precision for the decimal values. When i am entering a value in Line Edit the decimal values should not exceed more than 3 decimals. How can i set the precision for this decimals values?

    Example:
    123.456
    23456.057
    1.593.

    Note: i have to set the Precision only for the Decimal Values.

        Or, if you care about other nations, you can use this:
        @
        QLocale().toString( n, 'g', 3 )
        @
