How do I convert the string “39.9983%” into “39%” in C#?

Question

I don\'t want to do any rounding, straight up, \"39%\".

So \"9.99%\" should become \"9%\".

Answer 1

int.Parse("39.999%".Split('.')[0])

Doing this gives you a nice int that you can work with as you see fit. You can stick a % sign on the end with whatever string concatenation floats your boat.

Answer 2

I'm guessing you want a string returned? Probably the laziest way to do it:

    string mynum = "39.999%"
    mynum = mynum.substring(0, mynum.IndexOf('.'));
    mynum += "%";
    

To get an int, you could cast the result of line 2.

Answer 3

One way to do it:

"39.999%".Split(new char[] { '.' })[0] + "%";

Answer 4

Console.WriteLine("{0}%", (int)39.9983);

Answer 5

Probably a Regex. I'm no master of regular expressions, I generally avoid them like the plague, but this seems to work.

string num = "39.988%";
string newNum = Regex.Replace(num, @"\.([0-9]+)%", "%");

Answer 6

string myPercentage = "48.8983%";

string newString = myPercentage.Replace("%","");

int newNumber = (int)Math.Truncate(Double.Parse(newString));

Console.WriteLine(newNumber + "%");

There maybe hundred ways of doing this and this is just one :)
