Was ist der Zweck der StrictMath-Klasse in Java?

public final class StrictMath extends Object

public class StrictMathTest {
   public static void main(String args[]) {
      System.out.println("Absolute Value: " + StrictMath.abs(-100.50));
      System.out.println("Ceil Value : " + StrictMath.ceil(100.55));
      System.out.println("Floor Value : " + StrictMath.floor(100.55));
      System.out.println("Maximum Value : " + StrictMath.max(100,200));
      System.out.println("Minimum Value : " + StrictMath.min(100,200));
      System.out.println("Random Value : " + StrictMath.random());
      System.out.println("Round Value: " + StrictMath.round(100.75));
      System.out.println("Square Root Value : " + StrictMath.sqrt(2));
      System.out.println("PI Value: " + StrictMath.PI);
      System.out.println("Log Value: " + StrictMath.log(10.55));
   }
