NumericUpDown

A NumericUpDown is a number field with up and down buttons. Its value is a double.

<UIToolbox.NumericUpDown label="Qty" value="10" min-value="0" max-value="100" step="5" />
<UIToolbox.NumericUpDown label="Price" step="0.01" format-string="F2" />
<UIToolbox.NumericUpDown label="Cost" format-string="$#,0.00;($#,0.00)" />
<UIToolbox.NumericUpDown label="Tax" min-value="0" max-value="1" step="0.005" format-string="P1" />

Member	Description
`MinValue` (`min-value`), `MaxValue` (`max-value`)	The range. The value is clamped. A minimum above the maximum moves the maximum, and the other way around.
`Step` (`step`)	How much a button, a key or a wheel notch changes the value (1).
`FormatString` (`format-string`)	A .NET numeric format for the text, such as `F2`, `N0`, `P1` or `$#,0.00`. The text uses the invariant culture.
`TryParseText(text, out number)`	Reads a number in the look of `FormatString`, as the field does with typed text. Returns false for other text, such as an expression.
`Increment()`, `Decrement()`	Change the value by `Step`.

Hold a button to repeat the step. A button is disabled at its end of the range.
Up and Down (the arrow keys or the gamepad) change the value while the field has focus. They do not move focus. The mouse wheel also changes the value while the field has focus.
The typed text can be in the look of the format:
- Text and currency symbols before and after the number: "$1,234.50", "12.5 kg", "USD 5".
- Invariant group separators: "1,234,567". A lone comma, as in "1,5", is not a group separator.
- A negative number with a minus sign ("-$5", "$-5") or parentheses ("($5.00)").
- In a percent format (P, P1, or a custom format with "%"), a number in percent, with or without "%": "7.5 %" and "7.5" are 0.075. A format with "‰" reads per mille.
Other text goes to the DoubleField, so it takes expressions such as 2*8. In a percent format, an expression is not in percent: "5+5" is 10, not 0.1.
The standard C format shows the invariant currency sign "¤". For a real currency sign, use a custom format such as $#,0.00;($#,0.00).
Steps are rounded to 10 decimal places, so 0.1 three times is 0.3.
