# Java Round up Any Number

###### Posted By: Anonymous

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.

## Solution

`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
2
```
