pi() function in PHP
The pi() function Returns the value of Pi (π).Syntaxpi()ParametersNAReturnThe pi() function Returns the approximate value of PI. This value is a floating point value.3.1415926535898ExampleOutput3.1415926535898ExampleLet us see another example to get the value of PIOutput3.1415926535898
Read MoreDisplay complete date and time information using Formatter in Java
Firstly, create a Formatter and Calendar object.Formatter f = new Formatter(); Calendar cal = Calendar.getInstance();Now display the current date and time. We have shown the date here in both lowercase and uppercase −f = new Formatter(); System.out.println(f.format("Date and Time (lowercase): %tc", cal)); f = new Formatter(); System.out.println(f.format("Date and Time (uppercase): %Tc", cal));The following is an example −Exampleimport java.util.Calendar; import java.util.Formatter; public class Demo { public static void main(String args[]) { Formatter f = new Formatter(); Calendar cal = Calendar.getInstance(); ...

The rad2deg() function converts radian value to degree value. It Returns the equivalent of radia value val in degrees.Syntaxrad2deg(val)Parametersval − The radian value to be converted into degree.ReturnThe rad2deg() function Returns the equivalent of val in degrees.ExampleOutput180ExampleLet us see another example −Output90ExampleLet us see another example −Output22.5
Read MoreDisplay the day in week using SimpleDateFormat('E') in Java
To display the day in week, use the SimpleDateFormat(“E”) as shown below −Format f = new SimpleDateFormat("E"); String strDayinWeek = f.format(new Date()); System.out.println("Day in week = "+strDayinWeek);Since, we have used the Format and SimpleDateFormat class above, therefore import the following packages. With that, we have also used the Date.import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;Exampleimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MMMM/yyyy hh:mm:s"); ...
Read MoreImplicit conversion from 64-bit signed integer (long) to Decimal in C#
The long type represents a 64-bit signed integer.To implicitly convert a 64-bit signed integer to a Decimal, firstly set a long value.long val = 989678876876876;To convert long to decimal, assign the value.dec = val;Let us see another example −Exampleusing System; public class Demo { public static void Main() { long val = 76755565656565; decimal dec; Console.WriteLine("Implicit conversion from 64-bit signed integer (long) to Decimal"); dec = val; Console.WriteLine("Decimal : "+dec); } }OutputImplicit conversion from 64-bit signed integer (long) to Decimal Decimal : 76755565656565
Read MoreParse Octal string to create BigInteger in Java
To parse the octal string to create BigInteger, use the following BigInteger constructor and set the radix as 8 for Octal −BigInteger(String val, int radix)This constructor is used to translate the String representation of a BigInteger in the specified radix into a BigInteger.In the below example, we have set the BigInteger and radix is set as 8.BigInteger one, two; one = new BigInteger("12"); two = new BigInteger("4373427", 8);The following is the complete example −Exampleimport java.math.*; public class Demo { public static void main(String[] args) { BigInteger one, two; one = new BigInteger("12"); ...
Read MoreC# Program to determine the difference in hours between two dates
Set two dates.DateTime date1 = new DateTime(2018, 7, 15, 08, 15, 20); DateTime date2 = new DateTime(2018, 8, 17, 11, 14, 25);Now, get the difference between two dates.TimeSpan ts = date2 - date1;Get the result i.e. the difference in hours.ts.TotalHoursLet us see the complete code.Exampleusing System; using System.Linq; public class Demo { public static void Main() { DateTime date1 = new DateTime(2018, 7, 15, 08, 15, 20); DateTime date2 = new DateTime(2018, 8, 17, 11, 14, 25); TimeSpan ts = date2 - date1; Console.WriteLine("No. of Hours (Difference) = {0}", ts.TotalHours); } }OutputNo. of Hours (Difference) = 794.984722222222
Read MoreRight pad a string in Java
To right pad a string, use the String.format and set the spaces.String.format("%1$-" + 20 + "s", "demotext"));If you add 30 above, it will display the next string after 30 spaces from the beginning.String.format("%1$-" + 30 + "s", "demotext")The following is an example.Examplepublic class Demo { public static void main(String []args){ System.out.print(String.format("%1$-" + 20 + "s", "demotext")); System.out.println("Right padded!"); } }Outputdemotext Right padded!
Read MoreParse hexadecimal string to create BigInteger in Java
To parse the hexadecimal string to create BigInteger, use the following BigInteger constructor and set the radix as 16 for Hexadecimal.BigInteger(String val, int radix)This constructor is used to translate the String representation of a BigInteger in the specified radix into a BigInteger.In the below example, we have set the BigInteger and radix is set as 16 −Exampleimport java.math.*; public class Demo { public static void main(String[] args) { BigInteger one, two; String hexStr = "290f98"; one = new BigInteger("250"); // parsing two = new ...
Read MoreParsing and Formatting a Big Integer into Binary in Java
Firstly, take two BigInteger objects and set values.BigInteger one, two; one = new BigInteger("99"); two = new BigInteger("978");Now, parse BigInteger object “two” into Binary.two = new BigInteger("1111010010", 2); String str = two.toString(2);Above, we have used the following constructor. Here, radix is set as 2 for Binary for both BigInteger constructor and toString() method.BigInteger(String val, int radix)This constructor is used to translate the String representation of a BigInteger in the specified radix into a BigInteger.The following is an example −Exampleimport java.math.*; public class Demo { public static void main(String[] args) { BigInteger one, two; ...
