What is 2 + 2?

If you want accuracy in maths, you use something like Mathematica or Maple, since the IEEE 754 standard is inherently inaccurate. :)

Dude, you\'re confusing math with programming here. Funny things can happen with numbers, regardless of the mathematical implications, when programming the display of said numbers. I was pointing out that the difference can often lead to what appears to be a mathematical error when in fact it\'s just a display error. You\'re over thinking this by a long shot.

Arrr!

No, there isn\'t an entire thread about it. :3

It\'s about how 2+2 can =5.

Well, for the Capn\'t it is.

The post asked what is 2 + 2, since most would think the answer is 4, I merely pointed out that with a good old programming display error, you can get 5.

Arrr!

2 + 2 = 5 when using rounding on the screen can work, so long as the 2.4 is held in a double, float or other decimal format.

If there is more than one decimal point in a number, the number can not exist, so the argument is void, making the number zero.

1 + 1 = 10 because you are counting in binary, not whole numbers.

A + A = 20 because you are counting in hexadecimal or another system larger than decimal.

And to finish with a science joke.

Two men walk into a bar.

The first says 'I would like some H20.'

The second says 'That sounds great, I would like some H2O too.'

The second man dies.
