Rounding up

Projects Programming
1

Hi,
is there an easy way to "round up"?

2.2 --> 3
2.7 --> 3
2 --> 2

I could trunc() and add 1, but than I would have to check for the third case.

So is there an easier way to do?

2

Add a half and truncate.
2.2 does not normally round to 3.

3

ceil() does just that, it is the brother of floor() , trunc() and round()

void setup()
{
  Serial.begin(115200);
  int x = ceil(2.2);
  Serial.println(x);
  int y = ceil(2.7);
  Serial.println(y);
  int z = ceil(2.0);
  Serial.println(z);
}

void loop()
{
}
