Because there is a "bug" in it!!. It should say something like "overflow", because it's only designed to handle numbers that are a couple hundred digits long, or about 10^200. I'm just guessing.Somebody else might be able to give you the exact number that it can handle.
Well looky who is back! I thought you were still on your honeymoon with your HP. Did you two have a fight. Maybe the batteries went dead.
I was thinking about you when my science teacher tell us about the Carolina anole lizard. He said there are a lot of them around way more than there used to be. They make a good pet and my sister like to give them names and sometimes she ask me what is a good name. I will tell her to name him Retentive after you. Yep Anole-Retentive. If you ever make an account on here you can use that name. Hahahaha
To the first Anon, I type googolplex into the calculator and it says googolplex. Retentive like to complain a lot. Here is his post of questions which is mostly just complaints. He thinks there are bugs in the calculator but there are way more of them up his . . . . . .well you know where.
Oh I write an apology too but it not post. Maybe because it was too long. It is was a good one, maybe I try again.
