Certain input gives incorrect message when difference is equal to one one-millionth Is anyone else's solution giving the message "The numbers are not equal" when the two numbers input are 1.000001 and 1.000002? It's strange as I do receive the correct message when I use 1.000002 and 1.000003 (I.e. I am using the correct comparison operator)

The method works fine, but Judge doesn't accept it.Hi guys, I made the method workable, and it outputs precisely what it should, but the Judge doesn't accept my solution. My assumption is this is because of try-catch block, so fine, but can anyone give me a hint on what should I focus on to resolve it correctly? Thank you in advance!
