[Javascript] INCREDIBLE IE BUG!!!!

[Peter Brunone]

    Dang.  So now we need to round whenever performing floating point
operations...

    Any idea if this happens on previous versions of IE?

    Hi to all,

If I'm blind or dreaming, please, let me know, but, try this first:

It's easy to make the following sum in your head:  0.15 + 0.015 = 0.165
(OBVIOUS!)

TRY THIS IN YOUR IE 6 WITH SP1:  alert (0.15 + 0.015); you will obtain:
164999999999999998
OR:
alert (0.15 + 0.015 - 0.15 - 0.015);  - I think the result is obvious
for any human, but not for IE, that will return: -1.3877787807814457e-17
(that indeed, is almost 0, but not realy 0...).

I still can't believe it! And of course, those are not special numbers.
You can find many, many more (ex: 0.15+0.075, or 0.14+0.016) - I think
the bug is in the cases that the sum of the last digit of each number is
10, and the number of digits representing the precision is different.
