Tsukuld arrived to into Rohan by using a mithril coin to jump to first NPC in the WOLD quest chain…I otherwise would have had no idea of how to get there! So a wolding Tsukuld will go…and after that he will get his war pony!

Rohan is very pretty (am playing in very hi res graphics but may need to drop back to a lower setting if and when I get my war pony.)and its nice to be earning XP again, I already found the LI relic forger and deconstructor, essential under the circumstances. I can tell that my MisDeeds adventures have had a softening effect on my gameplay, where I wander carelessly into encounters…the pretty flora that hides some mobs does not help, in ROHAN this is decidedly dangerous, I am going to have to get cautious again.

It is very early days and am dissapointed to realise that I am still a quest chain away from getting my War pony, maybe only a 1/3 of the way!

0.3333333… (recurring) decimal representations of numbers can be tricky…

But I quite like the following explanation of the difficulties they can generate:

*‘Decimal numbers can be represented exactly, if you have enough space – just not by floating binary point numbers. If you use a floating decimal point type (e.g. System.Decimal in .NET) then plenty of values which can’t be represented exactly in binary floating point can be exactly represented.*

*Let’s look at it another way – in base 10 which you’re likely to be comfortable with, you can’t express 1/3 exactly. It’s 0.3333333… (recurring). The reason you can’t represent 0.1 as a binary floating point number is for exactly the same reason. You can represent 3, and 9, and 27 exactly – but not 1/3, 1/9 or 1/27.*

*The problem is that 3 is a prime number which isn’t a factor of 10. That’s not an issue when you want to multiply a number by 3: you can always multiply by an integer without running into problems. But when you divide by a number which is prime and isn’t a factor of your base, you can run into trouble (and will do so if you try to divide 1 by that number).*

*Although 0.1 is usually used as the simplest example of an exact decimal number which can’t be represented exactly in binary floating point, arguably 0.2 is a simpler example as it’s 1/5 – and 5 is the prime that causes problems between decimal and binary.’*

Maths is tricky… Rohan is pretty and my Little War Pony run is only one third of the first part done.
