What is %.2f? Why is it not just %f? Is there some additional calculation happening? The half function already does all the calculations including splitting the bill, so I’m not sure what %.2f is. (Btw why is this code not formatting correctly in lemmy?)
#include
#include
float half(float bill, float tax, int tip);
int main(void)
{
float bill_amount = get_float("Bill before tax and tip: ");
float tax_percent = get_float("Sale Tax Percent: ");
int tip_percent = get_int("Tip percent: ");
printf("You will owe $%.2f each!\n", half(bill_amount, tax_percent, tip_percent));
}
// TODO: Complete the function
float half(float bill, float tax, int tip)
{
bill += (bill * (tax / 100.0));
bill += (bill * (tip / 100.0));
bill /= 2;
return bill;
}
It’s a decimal floating point specifier with a precision sub-specifier.
This answer makes me so angry like revisiting trauma from learning programming. I just remember asking questions early on and getting answers more confusing that are even harder to parse
Which part of that is confusing to you? We can help make it easier to understand.
Edit: Oh, this isn’t even OP.
Its not confusion to me, I get what it is. Its the style of answer. Its like if you see a dog, ask what it is and someone answers Canis lupus familiaris.
There’s no grokking that. You either know or you don’t. If they’re asking what .2f then lots of answers here do a good job describing that it formats the value to two decimal places. We can all do something with that at any level.
Saying its a crombopulater sub cablator is much harder to process. It just seems like an answer thats likely to make the person to have to ask more questions or frustrated

…and gives you a link to the Wikipedia page about dogs.
It’s not a good answer in the sense that they did not do the work of copying and rephrasing the content of the website they linked, you have to do some of the work yourself. But it’s a very thorough answer that gives you all the information you need about formatting. Including examples of pretty much exactly the question OP asked.
