> 1/3 doesn't = 0.3333333, if it did equal that then would mean 0.33333333 x 3 = 1/3 x 3 > but as you have shown 0.33333333 x 3 = 0.99999999 > 1/3 x 3 =1 therefore 1/3 doesn't equal 0.33333333 exactly.. he started with a false equation then divided it with three and multiplies it back with 3 and is surprised to end up with the same false equation.. lol how dumb is that =) 参考:2007/10/20(土)00時33分07秒
