EBrown

Interesting, let me try it here quick.

@IsmaelMiguel So what's the problem?

Ismael Miguel

@RubberDuck Can you show the bit where you "split" the value into bytes?

@EBrown I'm doing number & 255, (number >> 8) & 255

RubberDuck

I already did. =)

LOL. I see the bug now...

[FieldOffset(1)] public byte Octet2;
[FieldOffset(3)] public byte Octet3;

EBrown

@RubberDuck That would do it...lol

Ismael Miguel

@RubberDuck off by one, in 2 places?

EBrown

9:10 PM

@IsmaelMiguel That should work fine (in many languages).

Ismael Miguel

@EBrown Exactly, and it "works"

EBrown

The only change I would make is to use the hex codes (to make it more clear).

Ismael Miguel

But then, I do byte[0] << 8 | byte[1]

And it doesn't work

EBrown

Is byte[0] a byte, or an int?

Ismael Miguel

A value between 0 and 255

EBrown

9:11 PM

It needs to be an int for that bitshift to work.

Right, but what type is it?

Ismael Miguel

Float.

(Javascript)

EBrown

I don't think you can do that with float values.

Ismael Miguel

But I can't get a number in Javascript.

Numbers are floats

Before then, Usenet was largely restricted to colleges and universities. Every year in September, a large number of incoming freshmen would acquire access to Usenet for the first time, and would take some time to become accustomed to Usenet's standards of conduct and "netiquette". But, after a month or so, these new users would either learn to comply with the networks...
