why "0.2" converted to double become 2?
I try below:
string _xx = "0.2";
double _d = Convert.ToDouble(_xx);
but it returns 2

7What is the decimal dot in your locale? – GSerg Jul 17 '20 at 07:20

2Running it in [dotnetfiddle](https://dotnetfiddle.net/P4OwgG) results in `0.2`, I'm guessing this is a locale problem – MindSwipe Jul 17 '20 at 07:21

i tried this in a console application and the output was `0.2` – Kardon63 Jul 17 '20 at 07:21

1Or to be more specific - is dot a group separator in your locale? – Alexei Levenkov Jul 17 '20 at 07:21

3Use `Convert.ToDouble(_xx, CultureInfo.InvariantCulture)`. Or better use [double.TryParse](https://learn.microsoft.com/en-us/dotnet/api/system.double.tryparse) instead. For example: `double.TryParse(_xx, NumberStyles.None, CultureInfo.InvariantCulture, out _d);`. – 41686d6564 stands w. Palestine Jul 17 '20 at 07:21

2`.` (dot) is a *thousand separaror* (not *decimal* one) in your *current culture* that's why the separator is *ignored*: `"123.456,78" => 123456.78`; `"0.2" => 02 => 2` – Dmitry Bychenko Jul 17 '20 at 07:27
