Your accuracy goes out of the window when you are actually measuring things though. The error is as significant as rounding 1/3 to 0.33

Not rounding. Mathematically, 0.(3) (repeating) is the exact same as 1/3

I know that. But practically, if you are trying to measure 1/3 of an arbitrary distance, or 1/3 of an arbitrary weight, you are not going to be able to hit the exact, precise measurement using normal household or kitchen tools. Therefore your origin assertion that 1/3 as a fraction is more accurate than decimal is meaningless, as you can't actually utilise that extra precision.
