It's so obvious that I don't even know know where to start. Just in case you're not trolling, just try javascript:0.0000000000002+0.7 (and then try it on your favorite language enforcing 32-bit floats -
FIOC is mostly unsuitable for this purpose).
Also note how for some strange reason the result has 16 decimal significant digits. Gee, I wonder how much 16*log(10)/log(2) is... Oh, that's right, just a little over 53. And it just turns out that 64-bit IEEE floats have 53 significant bits. Coincidence or conspiracy?
You be the judge.
