The following appears to be a pretty bad approximation. It really is, depending on how we look at it. However, when I change only one digit or, equivalently, when I remove one of its parts, it returns a perfect 10-digit result on my HP-41C, which I am using to evaluate it. BTW, I have used the HP-41C for this one because of its 10-digit display and a seldom used useful built-in function which most of my Voyagers lack. Too many tips, but it doesn't matter :-)

Have fun!

There hasn’t been any response to this puzzle, but it’s my fault. As I said, I forgot to mention something else had to be assumed. I will post the answer tomorrow, but I’ll give you another tip, in case you still want to give it a try. Remember numbers are not always what they look, as in the phrase “There are 10 types of people, those who understand binary and those who don’t”.
