I don't know if things have changed, but usually you have to be careful with testing equality of real numbers. Approximation errors might say two real numbers which "should" be equal are not. Maybe a better idea is to test if the difference is "small enough". (In the past, I had "sqrt(3)+1-1 == sqrt(3)" gave me FALSE... Now it doesn't, so maybe they've indeed changed things, but just in case...)
