Interesting number thread

However, zero / zero also returns undefined.

Huh?

Code:

public class Test {

public static void main(String[] args) {
System.out.println("Zero / Zero is: " + (0 / 0));
}

}

Result:

Exception in thread "main" java.lang.ArithmeticException: / by zero
at Test.main(Test.java:6)

This is exactly the same exception raising as (1 / 0).

I tried it in a calculator.

10 - the base of our numeric system and consequently, the metric system.

Also the modal number of fingers or toes on a person.

Actually, mathematically, division by zero is undefined. So you lose.

Side-note: The IEEE 754 Computer Standard for representing floating-point numbers in computers returns the standard's value of -+infinity, but the value itself meaningless; the associated Division by zero exception highlights this.

I was reading about this earlier too, and didn't realise + and - zero were held in floating point (as well as NaN and undefined, IIRC).

11

Easy way to multiply by 11 mentally: Starting from the rightmost digit (though I usually start from the left when doing it mentally) add its next-door neighbour digit to give an answer digit, not forgetting to carry when you do the next digit to the left of the current one, and continue like this until you run out of digits.

Still think it should be 0.

Now that's very handy. You don't know the number (no pun intended) of times I've been stuck on this at the checkout in Tesco. Cheers.

12

12 is an immensely important symbolic number in the Torah and Old Testament, and by continuation, the NT also.

Still think it should be 0.

Jesus, that's Microsoft software. Surprised it didn't print out 5.

Or Blue Screen.
