Rounding up a number to nearest multiple of 5

Question

Does anyone know how to round up a number to its nearest multiple of 5? I found an algorithm to round it to the nearest multiple of 10 but I can\'t find this one.

Answer 1

int roundUp(int n, int multipleOf)
{
  int a = (n / multipleOf) * multipleOf;
  int b = a + multipleOf;
  return (n - a > b - n)? b : a;
}
