For those who are curious, we round 9/2 = 4.5 to 4.0 at 1:23:20 because python follows the rule of Banker's Rounding (or Gaussian Rounding), which rounds a half to the nearest _even_ whole number. Therefore, 4.5 rounds to 4 as does 3.5.

oh i just thought two ints cant divide into a double so it has to be 4 but it is a double pointed float so youre right.

11//2 = 5, Its more about the // operator diving the numerator by whatever the denominator is then rounding down no matter what, even for something like 11/3 which would bring 3.66 will become 3 when using the floor // operator instead of the regular division

[@reymarckessaguirre5082]

@John Power there is a common defense among lawyers that argues saying "when you say 'literally', what you actually mean is a hyperbole of your sentence, other than actual 'literal'." This works on the concept that language is dynamic, meaning, word definitions changes depending on differrnt factors (study language if you want to know more, you sound like a guy who loves to learn. Dare yourself, literally). In this case, there is a clear message about Usama's comment. That is, the freeCodeCamp is a life-saver. There is no need to argue that what he means is something life-threatening since it is already given that his words are hyperbole. Also, your reply works on assumption that the only accepted definition of "literal" is the definition given by the dictionary. However, this is not the case, you are not writing a research paper or defending a case in a court, or any other instance that would require the usage of formal definitions. And even so, like what I have mentioned, when people say "literal" or "literally", in cases where there is little to no chance of ambiguity, what the person actually means is a hyperbole.

You start with what you need , you ensure your balance is sufficient , then you make the appriotiate time to do the shopping and then take everything you need.
