Single/Double.ToString() help

i cannot for the life of me figure out how to get this to return a string that is not formatted in scientific notation is there a simple guide or set of examples somewhere on how to use IFormatProvider? msdn doesn't seem to provide any examples edit: i found an example, it uses a mask... but why does the msdn page mention special characters (d/c/etc) for formating? where can i find a reference for the available masks?

You keep reading the wrong things. Did you try reading the documentation for the
NumberFormatInfo, which implementsIFormatProvider? You don't even need to specify this for numeric types instring.Format(or any other formatting method likeConsole.WriteLine). There's also a big section on formatting in the .NET Framework SDK, which should be your first stop for .NET-related documentation, articles, and examples. There is a simple solution for the scientific notation:string s = string.Format("{0:e}", myNum);
// OR
s = myNum.ToString("e"); // Also documented in numeric type's ToString docsMicrosoft MVP, Visual C# My Articles
