I just tried to solve the following equation with WolframAlpha and got some very weird results:
WolframAlpha tells me, one of the real solutions is x = 158847.000000000;
It also tells me that (of course) 158847.000000000 = 158847;
WA then tells me, that the equation using x=158847.000000000 is true;
But the same equation using x=158847 is false.
Shouldn't be 3) and 4) both true? Can anyone explain these results to me?
