Nevermind! have a good day.

Nevermind! have a good day.

What?

[Miss Yvonne]

Isn't that like one short of a full Excel spreadsheet?

Well, that's the answer but it isn't the whole answer. The conventional NFS anonymous/nobody UID is actually -2 --- but's that's 65534.

65534 is the twos-complement of -2 expressed as a 16-bit number. To represent negative numbers, you first make the ones-complement (flip even bit in the value expressed as a postitive number). You then add 1 to this value to get the twos-complement.

In our case we want -2 so we first express 2 as a binary 16-bit number.

0000000000000010 = 2
Now the ones-complement (flip every bit)
1111111111111101
Now the twos-complement by adding 1
1111111111111110 = 65534

in English:

When a computer stores a number in a 32bit part of memory it can go as high as 65534 (and as low as about -65534).

anything higher than that and you have to store it in a bigger part of memory..

Nicely done Boz. I forgot most people aren't as smart as I am.

I'm shocked you could ever forget that.

I'm not a programmer, but that even makes sense to this layperson. Thanks.

Now can you guys get our database folks at work to allow downloading from Business Objects into CSV files...I'm doing a fairly complex market analysis with limited tools and the damn 65K+change Excel spreadsheet limit is making me nuts.

I know you're gone.. but if you should read this -- import it into MS Access.

This is not accurate. It only takes 17 bits (not 32) to represent a range from -65536 (0x10000) to +65535 (0x0ffff) where bit 16 (the 17th bit) is the sign bit. To represent these numbers in 32 bits, -65536 would be 0xffff0000 and +65535 would be 0x0000ffff where bit 31 (the 32nd bit) is the sign bit. As you can see, the range that may be represented is considerably larger if using 32 bits. This range is -2,147,483,648 (0x800000000) to +2,147,483,647 (0x7ffffffff).

I sit corrected.

Can't believe he didn't know that.

[Eschie]

Ah, I didn't even notice the number before the question.

[allybear]

And I was just gonna say he's very popular!

Damn, Scotty's got a lot more PMs coming his way.

Let's get him some Midol.

This is still not as good as the Shakespeare thread.
