Example - Usage of log() method for double value

Following is an example of the usage of this method −

Example.groovy

class Example { 
   static void main(String[] args){ 
      double x = 11.635;
	  
      printf("The value of e is %.4f%n", Math.E); 
      printf("log(%.3f) is %.3f%n", x, Math.log(x));
   }
