Calculator: removing scientific notation in results?

This seems like it must be a bug or a corrupted app, but I'd just like to confirm: with the calculator in "basic" mode, dividing two numbers which only have one significant digit returns a result like so: 1/3000 = 0.000333 (the setting for decimal places seems to be irrelevant).

However, changing either number to have more than one significant digit returns the result in scientific notation, like so: 1/3100 = 3.225806e-04.

Can anyone else duplicate this or help me correct it? It's obnoxious to have to keep adjusting the numbers. And yes, I realize that means my math skills suck. Thanks in advance.
