> and the stunning browser-result: I haven't checked exactly what IEEE arithmetic should produce in that case, but why do you find it surprising? 1/100 can not be exactly expressed in binary floating point (just as 1/3 can not be expressed in finite length base 10 decimals). Since none of the three numbers you are adding up may be expressed exactly, and neither can the sum, it isn't surprising that any binary system used to encode the addition is out in the least significant position.
