public class Test {
public static void main(String[] args) {
System.out.println(15.12 + 59.70 - 74.82);
}
}
Drop that in 'Test.java', run 'javac Test.java', and then 'java Test'
(assuming you've got a Java SDK on your computer), and you'll see that
it's certainly not CF doing something weird. Maybe java's doing it
wrong, but I'd be surprised.
