I can't seem to find the answer I'm looking for regarding a simple question: how do I round up any number to the nearest int
?
For example, whenever the number is 0.2, 0.7, 0.2222, 0.4324, 0.99999 I would want the outcome to be 1.
So far I have
int b = (int) Math.ceil(a / 100);
It doesn't seem to be doing the job, though.
Math.ceil()
is the correct function to call. I'm guessing a
is an int
, which would make a / 100
perform integer arithmetic. Try Math.ceil(a / 100.0)
instead.
int a = 142;
System.out.println(a / 100);
System.out.println(Math.ceil(a / 100));
System.out.println(a / 100.0);
System.out.println(Math.ceil(a / 100.0));
System.out.println((int) Math.ceil(a / 100.0));
Outputs:
1
1.0
1.42
2.0
