Another useful feature is possibility to use scientific notation (e.g. 1.234e+18)
- for the widegt text. To enable this, negative precision should be specified either
+ for the widget text. To enable this, negative precision should be specified either
through a constructor or using setPrecision() method.
Note that "decimals" property of QDoubleSpinBox is almost completely substituted
a step value of 1.0 and a precision of 2 decimal places.
The value is initially set to 0.00.
