The Tuple class represents a 2-tuple, which is called pair. A tuple is a data structure that has a sequence of elements.It is used in −Easier access to a data set.Easier manipulation of a data set.To represent a single set of data.To return multiple values from a methodTo pass multiple values to a methodIt has two properties −Item1 − Get the value of the current Tuple object's first component.Item2 − Get the value of the current Tuple object's second component.ExampleLet us now see an example to implement the 2-tuple in C# −using System; public class Demo {    public static ...

The UInt16.CompareTo() method in C# is used to compare the current instance to a specified object or UInt16 and returns an indication of their relative values.SyntaxFollowing is the syntax −public int CompareTo (object val); public int CompareTo (ushort val;Above, the value for the 1st syntax is an object to compare. The value for 2nd syntax is an unsigned integer to compare.The return value is 0 if the current instance is equal to value. It’s less than zero if the current instance is less than val. The return value is more than zero if the current instance is greater than the ... Read More

The MathF.Truncate() method in C# is used to calculate an integral part of a specified single number or single-precision floating-point number.SyntaxFollowing is the syntax −public static float Truncate (float val);Above, Val is the specified number to be truncatedExampleLet us now see an example to implement the MathF.Truncate() method −using System; public class Demo {    public static void Main(){       float val1 = float.PositiveInfinity;       float val2 = float.NegativeInfinity;       Console.WriteLine("MathF.Truncate(val1) = "+MathF.Truncate(val1));       Console.WriteLine("MathF.Truncate(val2) = "+MathF.Truncate(val2));    } }OutputThis will produce the following output −MathF.Truncate(val1) = Infinity MathF.Truncate(val2) = -InfinityExampleLet us ...
