### Parameters
* **d** -- Any primitive data type.
### Return Value
Returns the arcsine value of the specified double-type parameter.
### Example
public class Test{ public 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("%.4f's arcsine value is %.4f degrees %n", Math.sin(radians), Math.toDegrees(Math.asin(Math.sin(radians))));}}
Compile and run the above program, the output result is:
The value of pi is 3.14160.7071's arcsine value is 45.0000 degrees
