That isn't an int But you would use T.Parse() or better yet, T.TryParse() where T is the type you want to parse into So in your case, some sort of a decimal type double, float, decimal, etc

Oo yeah no not a int indeed But needed to no how to Parse with C#

var str = "1.65";
if (double.TryParse(str, out var num))
{
    Console.WriteLine($"The value is {num}");
}
else
{
    Console.WriteLine("Not a valid number");
}

var str = "1.65";
if (double.TryParse(str, out var num))
{
    Console.WriteLine($"The value is {num}");
}
else
{
    Console.WriteLine("Not a valid number");
}

Console Output

The value is 1.65

if you want that double (or float if you want) to be int you can use Convert or Cast Just a heads up, Convert and Cast may yield different results

Angius•14mo ago

You will lose the decimal part though It'd be best to round it first, then cast to int

arion•14mo ago

Yes, Convert will round it up, cast will round it down

Angius•14mo ago

That way you have control over whether to round it, floor it, or ceiling it

TheOneAndOnlyOP•14mo ago

Its representive of a percentage, so the only thing I would maybe have to do is *100

var x = "1.69";
var ourFloat = float.Parse(x);
var roundedUp = Convert.ToInt32(ourFloat);
var roundedDown = (int)ourFloat;

Console.WriteLine($"Converted: {roundedUp}, Casted: {roundedDown}");

var x = "1.69";
var ourFloat = float.Parse(x);
var roundedUp = Convert.ToInt32(ourFloat);
var roundedDown = (int)ourFloat;

Console.WriteLine($"Converted: {roundedUp}, Casted: {roundedDown}");

Console Output

Converted: 2, Casted: 1

Converted: 2, Casted: 1
