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.
Example with pi.
#define PI 3.1415926 int main() { printf("%.2f", PI); // prints 3.14 return 0; }
man printf
.2f%means it will format to two decimal places max. So 5.877 will format as 5.88 and 1 will format as 1.00.
