textbox as below

1.722222222222222222222.

1.7E+20 isn't even close to 1.722222222222222222222, at least not by
floating point standards. Why do you want the latter when given the former?

First link searching for "numeric string format" on MSDN:
http://msdn.microsoft.com/en-us/library/dwhawy9k.aspx

The second link is this one:

Console.WriteLine ("{0:F0}", 1.7E+20) ;

The notation 1.7E+20 means 170 000 000 000 000 000 000 (170 quintillion,
following the US convention). E+20 doesn't mean "repeat the digit 2
twenty times", it means "multiply by 10 to the twentieth power".

You have two answers already in microsoft.public.dotnet.general. Both
answers are confused about how you are converting, as the two numbers don't
seem related to each other.
