A Bug In Maths, 81 divided by 2 error
If you divide 81 by 2 using the normal division method, you get 4.5 as the answer, when the answer should be 40.5
Discuss?

Code:
var int_val:Number = 81;
trace((int_val/2)); // 40.5
trace(81/2); //40.5
What are you talking about Adit?

Try dividing manually, the basic division technique taught in schools.

That's weird, if I try that, I am getting 31.77777(7 repeats infinitely). I think you're onto something here.

The way i was taught in school.
2 goes into 8, 4 times = 4
2 goes into 1, 0 times = 40
2 goes into 10, 5 times = 40.5
Or you can simply split it in half since we're dividing by 2, half of 80 is 40, half of 1 is .5
I don't know who taught you how to divide, but they did it wrong.

should not you be getting 20.5, okay it's division on units i.e., 8/4 and 2/4, so is 2.5

Try 'Long Division' method.
