I don't understand this comment at all. Most people are not computer programmers and therefore have no insight into how computers represent numbers. They just populate text fields in Excel, or whatever, with numbers. It's easier to use decimal points to do that than fractions.

When I'm not using computers or calculators, I do prefer American-style fractions over decimal point representations. Fractions are a lot easier for me to manipulate in my head. If I'm out in my garage, upside down, underneath a car, and trying to decide which drill bit to use, I don't have convenient access to the calculator on my cell phone or a pencil and paper, and reliable mental math is important. The fractions are easier, so that's what I want.
