Answer 1

Here are a few different examples to consider:

double l_value = 6;
string result= string.Format("{0:0.00}", l_value );
Console.WriteLine(result);

Output : 6.00

double l_value = 6.33333;
string result= string.Format("{0:0.00}", l_value );
Console.WriteLine(result);

Output : 6.33

double l_value = 6.4567;
string result = string.Format("{0:0.00}", l_value);
Console.WriteLine(result);

Output : 6.46
