Decimal places float

Question

I'm have a hard time trying to format a float with 4 decimal places, for example, I have the number 2.999995, I wanna get only 4 decimal places from this number, 2.9999, when I use .toString("#.####") or .toString("0.0000") it return 2.3000, I don't wanna this, I wanna 2.9999, someone can help me?

Thanks

I assume you mean 3.0000? If you want to show 2.9999, you don't want rounding - search for truncation. — Charles Mager, Jun 22 '14 at 13:49
ok, if I don't wanna round this number, I just wanna get the four decimal places — user3574907, Jun 22 '14 at 13:51

Try This:

float floatVal = 2.999995f;
string str=floatVal.ToString();
if(str.Split('.')[1].Length > 3)
    floatVal=Convert.ToSingle(str.Substring(0,str.IndexOf('.')+5));

Console.WriteLine(floatVal);

Output:

2.9999
