Why can't decimal numbers be represented exactly in binary?

What will be result of next code:

if(0.3 == ( 0.1 + 0.1 + 0.1 ))
{
      alert(true);
}
else
{
      alert(false);
}

It is strange, but result will be false.

Reason is that result of

0.1+0.1+0.1

will be

0.30000000000000004

How can be explained this behavior?
