kotlinlang

Today I tried to get the decimal of a float. Particularly I want to check if the decimal is `33` or `66`. So I wrote a function like `value - value.toInt()` which returns e.g. `0.33f`. I thought it works fine. But today I noticed that for some values it doesn’t work. For example: `8.33 returns 0.32999992`. I assume it's already a known bug? Anyway I found that very odd. Whats an efficient workaround?

```for(i in 0..8) {
    println("${8.33f - i}")
}
```
returns
```
8.33
7.33
6.33
5.33
4.33
3.33
2.33
1.3299999
0.32999992
```
1.3.50 jvm

I didn't know that the floating point issues happen at that absurdly simple code. Sorry for questioning the kotlin language :grimacing: I ended up with ```"%.2f".format(value - value.toInt())```

You don’t have use strings, though. You can do: `round((value - value.toInt()) * 100) / 100`.

It works like a charm after adding `f` at the very end. Thanks a lot! ```round((value - value.toInt())*100)/100f```
