When my calculator says 1E15 (but the E is smaller), what does that mean?
When my calculator displays 1E15 (with the "E" appearing smaller than the numbers), what does this notation signify? I would appreciate any insights or explanations regarding this format. Thank you!

The "E" means "times 10 to the power of". So in this case, your example would mean: 1.0 x 10^15.

The Answer to Life, the Universe, and Everything has a numeric solution in Douglas Adams’ series The Hitchhiker’s Guide to the Galaxy. In the story, a "simple answer" to The Ultimate Question is requested from the computer Deep Thought—specially built for this purpose. It takes Deep Thought 7½ million years to compute and check the answer which turns out to be 42. Unfortunately, The Ultimate Question itself is unknown – suggesting on an allegorical level that it is more important to ask the right questions than to seek definite answers.
your calculator is showing what the exponent is on a x 10^x
ie 1E15 is 1×10^15 or 2.5E7 is 2.5×10^7.
