Oh, what fun!

Today at work there was a calculator sitting on the desk. As the hours ticked by, I noticed that it read:

0.0000014

Why would it say that? Did someone type it there intentionally? Was it the end of a long, complex problem that was waiting to be continued when the desk owner returned? Secretly, I decided to create some mischief. I cleared the calculator and typed:

0.0000015

I smiled to myself, but not enough to catch a student's wandering eye and arouse their suspicions. No one will ever know!

Such was the highlight of my day.
