Webdouble round (double x); float round (float x);long double round (long double x); double round (T x); // additional overloads for integral types Round to nearest Returns the integral value that is nearest to x , with halfway cases rounded away from zero. WebThe reason the rounding doesn't work is because dividing two ints in C gives you another integer. Think about doing long division and how you would get an answer and a remainder. The / operator gives you the answer and the % operator gives you the remainder. So 5 / 2 = 2 but 5 % 2 = 1 (the remainder).
