Groovy - asin() method

---

---

The asin() method returns the arcsine of the specified double value.

Syntax

double asin(double value)

Parameters

• value − A double data type.

Return Value

This method returns the arcsine of the specified double value.

Example - Usage of asin() method for a positive double value

Following is an example of the usage of this method −

Example.groovy

class Example { 
   static void main(String[] args) { 
      double degrees = 45.0; 
      double radians = Math.toRadians(degrees);
	  
      System.out.format("The value of pi is %.4f%n", Math.PI); 
      System.out.format("The arcsine of %.4f is %.4f degrees %n", 
      Math.sin(radians), Math.toDegrees(Math.asin(Math.sin(radians))));  
   } 
}

Output

When we run the above program, we will get the following result −

The value of pi is 3.1416 
The arcsine of 0.7071 is 45.0000 degrees

Example - Usage of asin() method for zero double value

Following is an example of the usage of this method −

Example.groovy

class Example { 
   static void main(String[] args) { 
      double degrees = 0.0; 
      double radians = Math.toRadians(degrees);
	  
      System.out.format("The arcsine of %.1f degrees is %.4f%n", degrees, Math.toDegrees(Math.asin(Math.sin(radians))));
   }
}

Output

When we run the above program, we will get the following result −

The arcsine of 0.0 degrees is 0.0000

Example - Usage of asin() method for negative double value

Following is an example of the usage of this method −

Example.groovy

class Example { 
   static void main(String[] args) { 
      double degrees = -45.0; 
      double radians = Math.toRadians(degrees);
	  
      System.out.format("The arcsine of %.1f degrees is %.4f%n", degrees, Math.toDegrees(Math.asin(Math.sin(radians))));
   }
}

Output

When we run the above program, we will get the following result −

The arcsine of -45.0 degrees is -45.0000
