double num = 3.14159265358979323846; string str = StringHelper.AccuracyToString(num, 2); Console.WriteLine(str); // output: "3.14"
float num = 1.23f; string str = StringHelper.AccuracyToString(num, 4); Console.WriteLine(str); // output: "1.2300"In this example, we have a float value num which we want to convert to a string with 4 decimal places. We use the AccuracyToString method and specify the number of decimal places we want as the second argument. The resulting string is "1.2300". It's possible that StringHelper is a custom class or library, but without more context it's impossible to determine the exact package/library.
