String formating within C#
Below is an example of using string formating to print a time
int h = 12;
int m = 13;
int s = 14;
string myString = string.Format("{0}:{1}:{2}", h, m, s);
Console.WriteLine(myString);
To format a number to two decimal places, you could use the string format.
double s = 14.123;
string myString = string.Format("{0:0.00}", s);
Console.WriteLine(myString);
