To convert a Double value to an Int64 value, use the Convert.ToInt64() method.Int64 represents a 64-bit signed integer.Let’s say the following is our double value.double val = 23.951213e12;Now to convert it to Int64.long longVal = Convert.ToInt64(val);Let us see the complete example.Example Live Demousing System; public class Demo { public static void Main() { double val = 23.951213e12; long longVal = Convert.ToInt64(val); Console.WriteLine("Converted double {0:E} to Int64 {1:N0} value ", val, longVal); } }OutputConverted double 2.395121E+013 to Int64 23,951,213,000,000 value

The Any method checks whether any of the element in a sequence satisfy a specific condition or not.If any element satisfy the condition, true is returned.Let us see an example.int[] arr = {5, 7, 10, 12, 15, 18, 20};Now, using Any() method, we will check whether any of the element in the above array is greater than 10 or not.arr.AsQueryable().All(val => val > 5);If any of the element satisfies the condition, then True is returned.Let us see the complete example.Example Live Demousing System; using System.Linq; class Demo { static void Main() { int[] arr = {5, 7, ...

To convert a Double value to an integer value, use the Convert.ToInt32() method.Int32 represents a 32-bit signed integer.Let’s say the following is our double value.double val = 21.34;Now to convert it to Int32.int res = Convert.ToInt32(val);Let us see the complete example.Example Live Demousing System; public class Demo { public static void Main() { double val = 21.34; int res = Convert.ToInt32(val); Console.WriteLine("Converted double {0} to integer {1} ", val, res); } }OutputConverted double 21.34 to integer 21
Byte represents an 8-bit unsigned integer.Implicit conversion of an 8-bit unsigned integer (Byte) to a Decimal is possible. Let us see how.Here’s our Byte value.byte val = 16;To implicitly convert, just assign the value as shown below −decimal dec; dec = val;Let us see the complete example.Example Live Demousing System; public class Demo { public static void Main() { byte val = 16; decimal dec; // implicit dec = val; Console.WriteLine("Decimal ="+dec); } }OutputDecimal =16
Implicit conversion of a 32-bit unsigned integer (UInt) to a Decimal requires you to first declare a UInt.uint val = 342741539;Now to convert it to decimal, just assign the value.decimal dec; // implicit dec = val;Example Live Demousing System; public class Demo { public static void Main() { uint val = 342741539; decimal dec; // implicit dec = val; Console.WriteLine("Decimal = "+dec); } }OutputDecimal = 342741539
To find the average of integers in C#, use the Queryable Average() method.Let’s say the following is our integer array.var arr = new int[] { 10, 17, 25, 30, 40, 55, 60, 70 };Now, use the Average() method to get the average of the elements.double avg = Queryable.Average(arr.AsQueryable());Example Live Demousing System; using System.Linq; class Demo { static void Main() { var arr = new int[] { 10, 17, 25, 30, 40, 55, 60, 70 }; double avg = Queryable.Average(arr.AsQueryable()); Console.WriteLine("Average = "+avg); } }OutputAverage = 38.375
To cast elements, use the Cast() method.The following is our list.List myList = new List { "Mac", "Windows", "Linux", "Solaris" };Now, cast and use the Cast() method with substring() method to display the first two letters of every string in the list.IEnumerable res = myList.AsQueryable().Cast().Select(str => str.Substring(0, 2));Let us see the complete example.Example Live Demousing System; using System.Linq; using System.Collections.Generic; class Demo { static void Main() { List list = new List { "keyboard", "mouse", "joystick", "monitor" }; // getting first 2 letters from every string IEnumerable res = list.AsQueryable().Cast().Select(str => ...

Use the toExponential() method to force a number to display in exponential notation, even if the number is in the range in which JavaScript normally uses standard notation.The following is the parameter −fractionDigits - An integer specifying the number of digits after the decimal point. Defaults to as many digits as necessary to specify the number.ExampleYou can try to run the following code to force a number to display in exponential function − Javascript Method toExponential() var num=77.1234; var ...

The toLocaleString() method returns a string value version of the current number in a format that may vary according to a browser's local settings.ExampleYou can try to run the following code to return a string value version − JavaScript toLocaleString() Method var num = new Number(150.1234); document.write( num.toLocaleString());
