Whta??!

There's been something playing on my mind this weekend that I just can't get over... I can't understand how there is a flaw in this simple but contradictory maths.You see the problem is this:

A third times 3 is clearly 1 whole right? But then when you convert a third to its decimal equivalent it is 0.3 recurring. Now multiply 0.3 recurring by 3 and you will get 0.9 recurring. Surely it should be 1?! Now I see that 0.9 recurring can be rounded to one without losing much accuracy but it is still incorrect to say that 0.9 recurring is equal to 1, right? Right? Oh my goodness... My stupid calculator messed it up because it converts everything into fractions! I wonder what my old calculator would have done...
