[c#] Formatting a float to 2 decimal places

As already mentioned, you will need to use a formatted result; which is all done through the Write(), WriteLine(), Format(), and ToString() methods.

What has not been mentioned is the Fixed-point Format which allows for a specified number of decimal places. It uses an 'F' and the number following the 'F' is the number of decimal places outputted, as shown in the examples.

Console.WriteLine("{0:F2}", 12);    // 12.00 - two decimal places
Console.WriteLine("{0:F0}", 12.3);  // 12 - ommiting fractions
