The Golden Castle

There is an ancient legend...

Before Dragons, before Mathias's Invasion,

Before the Crusader Kings, before even the Black Falcons,

There was an ancient castle

Made of pure gold...

Facebook buy and sell groups can be great (or terrible, depending on your viewpoint). Just up the road in Penguin, this legendary castle popped up for sale.

Now, of course, compared to later Lego castles it looks pretty stupid (I mean, why yellow?).

But this particular set occupies a very important place in the history of Lego. This was the first minifig scale castle Lego produced (there was an earlier castle but that was in the days before minifigs). This was the first time that Lego knights and swords and things were produced. 

This castle was released in 1978, as part of the standard Lego town theme. The seperate Castle theme didn't come along until a few years later when they released more sets. The Lego Castle theme was huge, and has remained popular even since (although the current Nexo Knights is a bit of an embarrassment).

The various patterns on these original shields and torsos etc are all stickers - so finding them in this condition is pretty incredible. For toys that are almost 40 years old - they are in fantastic nick!

So - another of my bucket list ticked off. Finally made it up to Bathurst for the Great Race!

It’d been something I wanted to do for ages, but it hadn’t ever really been viable - until Jason mentioned that he had a mate living in Bathurst that he could crash with. Well, that was enough motivation - we decided we should try and get up there.

Turns out that Jason’s mate was actually his Dad’s mate that Jason had never met - but that was still good enough - so we organised to pitch a tent in his back yard and headed up.

We took Friday off and basically drove all day to get up there - and spend Saturday and Sunday at the circuit. We found a nice spot on Skyline to watch the race. It wasn’t the best spectator spot, but it had the advantage of having a big screen close by, so combined with our radios we could actually keep tabs on what was going on - which would have been almost impossible at some of the ‘better’ spots.

Such as Forest Elbow - that was a much more spectacular spot - but no screens. The race is well and truly long enough to move around a bit though.

Far out the track is steeper than it looks though. I can see it on the TV now, but until you’ve been around the track you don’t realise how insane it actually is.

On the Monday we hunt around in Bathurst for a while - and eventually the track was opened so we could drive the circuit. Of course, the speed limit is 60km so it wasn’t exactly a flying lap - but I’m very glad to say I’ve driven around it now.

The race itself was awesome too - even if it wasn’t a brilliant day for Ford.

So the other weekend Jason and I went for a drive in the Forester.

Just a short jaunt up to Bathurst in NSW. Almost 1600km round trip from where we got off the Spirit. 

Got to say, some of the roads were a little more interesting than I'd expected (see photo). I blame Jason's navigating.

Almost 800km in a day, I'm pretty sure that's the longest I've travelled in a car, and it's certainly the longest I've driven. Not a bad drive though.

We split the return trip over two days. We could have done it in a single day, but we didn't want to risk missing the boat.

It also gave us time to stop at a Toyworld in the town of Young. I love rural Toywords because they often still have older stuff on the shelves - but even I was shocked to see this on the shelf. Lego 9v track hasnt been available for years! It's not on the shelf anymore :)

Ok - so I’m certainly no mathematician as anyone who knows me can attest - but even I can tell that 196 + 2.91 - 196 - 2.91 equals zero. 

196
2.91
-196
-2.91

The negative numbers cancel out the positive, and you’re left with zero.

Unless you ask Excel, that is.

I use Excel quite a bit, but this is the first time I’ve come across this particular problem. According to Excel, the result is -3.55271E-15.

There’s nothing hiding in those numbers (type them in yourself and test). Excel just can’t hack it. If you change the order of the numbers it sometimes gets it right.

You can force it to change the formatting and that will hide the odd result and appear as zero - but it’s only hiding the issue.

So what’s going on?

I’ve tried multiple computers and different versions of Excel and had the same result.

I’m still not really sure what’s going on here - but from what I can dig up, it’s got to do with the fact that Excel uses floating point numbers, and they aren’t precise enough. So it actually is just getting it wrong.

This is an issue with floating point numbers, not Excel itself. I used floats in SQL and had the same result.

This is the first time I’ve come across this sort of issue by accident. Took me ages tearing my hair out trying to work out why my data wasn’t reconciling. Turns out that it was - if you discount the issue.

I'm slightly less embarrassed by my lack of Mathematical ability when I can get this right and a computer can't.

Trust me - regardless of what Excel says, the answer is zero.
