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

I don’t want to do any rounding, straight up, `"39%"`.

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

,

I hope this will work.

string str = “39.999%”;

string Output = str.Split(‘.’);

Thanks

``````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 ðŸ™‚

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+)%", "%");
``````

,

One way to do it:

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

,

``````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.

Now we have two questions asking the same thing..

Heres my crack at it.

``````"39.9983%".Split('.')0 + "%";
``````

,

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

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.
