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
The deg2rad() function converts degree to radian value. It Returns the radian equivalent of the specified degree value.Syntaxdeg2rad(num)Parametersnum − The degree value to be converted to radian.ReturnThe deg2rad() function Returns the radian equivalent of the specified degree value.Example Live DemoOutput360 degrees converted to 6.2831853071796 radians!Let us see another example −Example Live DemoOutput0.785398163397451.57079632679493.14159265358984.71238898038476.2831853071796
The exp() function Returns ex. This is e raised to the power x.Here,'e' is 2.718282 x is the powerSyntaxexp(x)Parametersx = The exponentReturnThe exp() function Returns e raised to the power of x, which is a float value.Example Live DemoOutput12.718281828459Let us see another example −Example Live DemoOutput7.3890560989307148.41315910258485165195.40979
One of the methods of the Timer class is the cancel() method. It is used to terminate the current timer and get rid of any presently scheduled tasks.The java.util.Timer.cancel() method is declared as follows −public void cancel()Let us see a program which uses the cancel() methodExample Live Demoimport java.util.*; public class Example { Timer t; public Example(int seconds) { t = new Timer(); t .schedule(new Running(), seconds); } class Running extends TimerTask { public void run() { System.out.println("Task is cancelled"); ...
