I have this script:

```auto
on(release){
 _global.combospeed -= 0.1;
}

```

and the same with + version.  
I also have a dynamic text where the combospeed is show.  
But when I do - 0.1 at 9.6 --\> 9.5 it doesnt subtract by 0.1, but by 0.0999999999  
WHY?!  
it also adds 0.099999999 at 9.5 --\> 9.6  
WTF is wrong with actionscript? xD
