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.

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

An operating system isn’t a car or a machine that needs to maintain running hours for optimal performance. If I have an operating system that I only need for one specific function, and only use it for that function, once or twice a month, there is no reason that that operating system should fail to do the one thing I need it to do every time I turn it on.

Yeah but, despite all of that, (none of which I read, I’m sure it’s all true though), it is a natural law of the universe that you cannot get more energy out of a system than you put in. Regardless of all other factors, if you consume upto your daily maintenance calorific intake, you cannot gain weight. If you consume less, you WILL lose weight. Whether external factors or pressures prevent you from managing your calorific intake correctly in another discussion, but the laws of thermodynamics don’t take a break when it comes to health and nutrition.

It’s addictive, not addicting.
