The zip_entry_close() function is used to close a zip archive opened by the zip_entry_open() function.Syntaxzip_entry_close(zip_entry)Parameterszip_entry − The zip entry resource. Required.ReturnThe zip_entry_close() function Returns TRUE on success and FALSE on failure.The following is an example. Let’s say we have "new.zip" file as our archive.Example
The zip_entry_compressed_size() function returns the compressed file size of a zip archive entry.Syntaxzip_entry_compressed_size(zip_entry)Parameterszip_entry − The zip entry resource. Required.ReturnThe zip_entry_compressed_size() function returns the compressed file size of a zip archive entry.The following is an example that gets the size of the files in "new.zip" archive.ExampleOutputCompressed: 90 Compressed: 12 Compressed: 67
The is_nan() function checks for ‘not a number’ value. It Returns TRUE if num is 'not a number', else FALSE is Returned.Syntaxis_nan(num)Parametersnum − The value to checkReturnThe is_nan() function Returns TRUE if num is 'not a number', else FALSE is Returned.ExampleLet us see another example −Example
The lcg_value() function Returns a pseudo random number in the range 0 - 1Syntaxlcg_value()ParametersReturnThe lcg_value() function Returns a pseudo random float value in the range 0 - 1.Example Live DemoOutput0.42510822828987Let us see another example generating different values every time lgc_value() function is used.Example Live DemoOutput0.0016752472603958 0.95593815480995 0.57392418877843 0.1374706663408
To get the arc tangent of a given value in Java, we use the java.lang.Math.atan() method. The atan() method accepts a double value whose angle needs to be computed. The range of the angle returned lies in the range -pi/2 to pi/2. If the argument is NaN, then the result is NaN.When the argument is zero, then the output is a zero with the same sign as the argument.Declaration −The java.lang.Math.atan() method is declared as follows −public static double atan(double a)where a is the value whose arc tangent is computed.Let us see a program to get the arc tangent of ...

To get the arc cosine of a given value in Java, we use the java.lang.Math.acos() method. The acos() method accepts a double value whose angle needs to be computed. The range of the angle returned lies in the range 0 to pi. If the argument is NaN or greater than 1 or less than -1 then the result is NaN.Declaration −The java.lang.Math.acos() method is declared as follows −public static double acos(double a)Here, a is the value whose arc cosine is computed.Let us see a program to get the arc cosine of a given value in Java.Example Live Demoimport java.lang.Math; public class ...

The mt_getrandmax() function Returns the largest possible random value.Syntaxmt_getrandmax()ParametersNAReturnThe mt_getrandmax() function Returns an integer value, which is the largest possible random value.Example Live DemoOutput2147483647
The mt_srand() function seeds the Mersenne Twister random number generator.Note − Random number generator is seeded automatically after the release of PHP 4.2.0. This function is not needed now.Syntaxmt_srand(seed)Parametersseed − The seed valueReturnThe mt_srand() function Returns nothing.Example Live DemoOutput1320295657
The decoct() function converts a decimal number to an octal. It Returns an octal string of the specified decimal.Syntaxdecoct(num)Parametersnum − The decimal value to convert.ReturnThe decoct() function Returns an octal string of the specified decimal.Example Live DemoOutput106Let us see another example −Example Live DemoOutput72547141460
The Timer Class in Java is a facility for threads to plan tasks for future execution in a background thread. Tasks may be executed a single time or multiple times. The Timer class is thread-safe i.e. the threads of the class do not require external synchronization and can share a single Timer object. A point to be noted is that all constructors start a Timer thread.The Timer Class in Java came into existence since JDK 1.3. This class ascends up to large numbers of concurrently scheduled tasks. Internally, it uses a binary heap in the memory to represent its task ... Read More
