Error with JQPlus Question

I was working on this question and this was the answer. When I ran it on my machine, I came up with "True".
The following code will print 'false'.
float f = 1.0F/3.0F;
System.out.println( (f * 3.0F) == 1.0F );

I think you are correct. I tried this code. The output is also TRUE.

Thanks - I just wanted to make sure I wasn't looking at something wrong.

I think the point of it is it will not always print true on every machine. Since float values lose precision, when you do 1.0F/3.0F you may get .333333333334 and then when you mutiply that by 3.0f you may get 1.00000000001 which won't equal 1.0f.

Hi guys,
I guess there is no error,
As the question is,"will the code below print, false"
So the answer has to be false....as you all know that, the code will print "true".
NO ERROR....it's the way you read the question
