To get the hyperbolic arc-cosine of a floating-point value, the code is as follows −Exampleusing System; public class Demo {    public static void Main() {       float val1 = 0.1f;       float val2 = 0.9f;       Console.WriteLine("Angle (val1) = "+(MathF.Acosh(val1)));                                 Console.WriteLine("Angle (val2) = "+(MathF.Acosh(val2)));    } }OutputThis will produce the following output −Angle (val1) = NaN Angle (val2) = NaNExampleLet us see another example −using System; public class Demo {    public static void Main() {       float val1 = 5.1f;       float val2 = 8.9f;       Console.WriteLine("Angle (val1) = "+(MathF.Acosh(val1)));       Console.WriteLine("Angle (val2) = "+(MathF.Acosh(val2)));    } }OutputThis will produce the following output −Angle (val1) = 2.312634 Angle (val2) = 2.876027

To check whether the specified character has a surrogate code, the code is as follows −Example Live Demousing System; public class Demo {    public static void Main() {       string str = new String(new char[] { 'k', 'm', 'g', 't', '\uD800' });       bool res = Char.IsSurrogate(str, 4);       if (res)          Console.WriteLine("Contains Surrogate value!");       else          Console.WriteLine("Does not contain Surrogate value!");    } }OutputThis will produce the following output −Contains Surrogate value!ExampleLet us see another example − Live Demousing System; public class Demo {   ...
