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 ...

For this, use group by. Let us first create a table −mysql> create table DemoTable1344 -> ( -> `SequenceId` int NOT NULL AUTO_INCREMENT PRIMARY KEY, -> ClientId int, -> isMarried tinyint(1) -> ); Query OK, 0 rows affected (0.49 sec)Insert some records in the table using insert command −mysql> insert into DemoTable1344(ClientId, isMarried) values(4567, 0); Query OK, 1 row affected (0.45 sec) mysql> insert into DemoTable1344(ClientId, isMarried) values(9876, 0); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable1344(ClientId, isMarried) values(5432, 1); Query OK, 1 row affected (0.12 sec) mysql> insert into DemoTable1344(ClientId, isMarried) ...

The :first selector in jQuery is used to select the first DOM element.SyntaxThe syntax is as follows −$(":first")ExampleLet us now see an example to implement the :first() selector − .demo { background-color: red; color: white; font-size: 16px; border: 2px blue dashed; } $(document).ready(function(){ $("input:first").addClass("demo"); }); Job Application Applicant Name: Rank: Resume: OutputThis will produce the following output −
The Convert.ToBase64CharArray() method in C# is used to convert a subset of an 8-bit unsigned integer array to an equivalent subset of a Unicode character array encoded with base-64 digits.SyntaxFollowing is the syntax −public static int ToBase64CharArray (byte[] arr, int offsetIn, int length, char[] outArray, int offsetOut);Here, arr − An input array of 8-bit unsigned integers.offsetIn − A position within arr.length − The number of elements of arr to convert.outArray − An output array of Unicode characters.offsetOut − A position within outArray.ExampleLet us now see an example to implement the Convert.ToBase64CharArray() method −using System; public class Demo { public ...
