If I had only known this in college. We students heard “One two seven dot zero dot zero dot one” a lot from professors. This could’ve been a really fun inside joke. And then on the last day of class, “Yeah, 127.1 is the same thing, and that’s what I’ve been typing this whole time.” The look on their face!

We can’t change the past, but we can the future. If you know someone who’s a computer science student, arm them with this.
