NumericUpDown decimal places replace with 0 in persian culture

[HamidSepehry]

Describe the bug
in the sample application, when I select the Persian culture and input a decimal number such as 12.751, the input number changes to 12.000 when I leave the control.
I debugged it and realize that in Persian culture, NumberDecimalSeparator property sets to '/'. and the number: 12.751 informed to 12/751. So the TryGetNumberFromText() method cannot get the full part of that as a number and returns 12 instead of 12.751

So I fix this issue by changing the code below in the ValidateText method inside of NumbericUpDown class:

//var number = TryGetNumberFromText(text, isHex);
var number = TryGetNumberFromText(text.Replace(this.SpecificCultureInfo.NumberFormat.NumberDecimalSeparator, "."), isHex);
number = number.Replace(".", this.SpecificCultureInfo.NumberFormat.NumberDecimalSeparator);

I just want you to commit that part of the code in the main project and release a new branch into NuGet. thank you.
