NumericUpDown

The NumericUpDown control lets the user enter and edit numeric values. You can set the minimum and maximum values as well as the step change made when the spinner is used. The value of the control can also be set by commands from a connected device.

The NumericUpDown control is a Decimal value, even if you set the number of decimal places to zero.
