Switch machine model

The Q direction values seem to retain 5 digit precision. ... While not critical to the future of the World, it would be interesting to know where the properties box gets it's info, when I thought it should be based on what's in the w file. And why some objects get 5 digit precision on the Y and not others.

I agree, I've pondered the same things myself. As I said above, my theory is that precision gets trickier the furthest from the center a world tile because the numbers get larger. I haven't put that theory to the methodical test, yet. My basis for that theory is the way computerized floating-point numbers work: the more digits to the left of the decimal point, the fewer you can have on the right (and vice-versa). With the complex math involved in rendering the world (even as simply as MSTS does it) all of them numbers get related really quickly.

Meanwhile, I have to say I've had enough of Vince in this thread. He's completely out to lunch if he thinks he should be patted on the back for having an epiphany about thousandths of a meter. The metric system has been around long enough that the majority of us "get it" without having to think about it as hard as he has to. I have completely lost any respect I ever had for the man. I have tried to be cordial about this but enough is enough. I will publicly declare right now that I have read my posts in this thread several times, and have not found myself to have portrayed anything here as fact that wasn't*. Therefore, I have nothing to retract! If anyone has any questions or concerns about anything I've said, they're welcome to contact me directly in private. I will not be baited into another public pissing contest, but I will stand up for myself and correct myself when due.

Something I realized during all of this: there always has to be some rounding, because if there weren't, then each value in the .w files and beyond could have an infinite number of digits!

*I really have experienced rounding with Y coordinates (Vince really did tell me I haven't), I really never said we need better than millimeter precision for object positioning, Vince really did suggest Jean to use the Terrain Object setting even though Jean already said he was, Vince really did repeatedly say the fourth decimal place splits a millimeter (the third decimal place) 1000 times, Vince really can't critically analyze his own writing, Vince really stated world object X/Z coordinates go from -2048 to 2048 on a world tile, I really have not confused terrain Y values with object positioning Y values, Vince really does rudely yell WRONG! at people, Vince really did announce that me saying 0.0001 meters is one 1/1000th of a millimeter is wrong is incorrect, Vince really does get irate at people who don't listen to him (even if he's repeatedly wrong), and I really can handle being told I'm wrong if I'm actually wrong! Vince is right the End key doesn't do anything when moving objects, but then I never actually said it did.Cl

It's way overdue Joe.

"...my theory is that precision gets trickier the furthest from the center a world tile because the numbers get larger."

But, Joe, all Jean wanted was a precision Y axis adjusting method rather than 'Key tapping'? And now this? Oh well . . . so it goes.

A tile is a 2 kilometer square divided into a 2048 x 2048 grid. Are you saying the subtiles (squares) are bigger (or smaller??) near the tile border. That's a new one on me.

As a 2km grid equally subdivided has equal sized subtiles and the tile coordinate addresses do (of course) get 'larger' moving away from center(0 to 1024), but I don't see what that has to do with Y axis decimal precision???
Help me out as I'm not too clear what you mean by this.

Meanwhile, I have to say I've had enough of Vince in this thread.

Joe, I've actually not had enough of you!
I am now actually enjoying your thrashin and attempting to duck away from this.
And while you ponder that, Who was it jumped in with rounding & powers theorys when when all I did was to provide a precision method to move static obects on the Y axis.

Here's my post #15, responding to your 'theories'. Please read the THIRD sentence of my response.

JOVET: "Unfortunately there's a problem with that. The Route Editor and MSTS like to play rounding games. Sometimes it won't let you adjust things by the millimeter, and sometimes it will. It gets a bit annoying sometimes..."

My response was:
"WRONG in this case Joe!! Rounding is not a problem when manually setting the Y axis of objects.MSTS WILL round decimals >4 decimal places but not less."

So I'm not allowed to say you're 'wrong' is it? Why? You are clearly wrong so I can't say you're right. That would be a lie! The editors DONT round object Y axis <4 decimals. FACT!

I'm sure you HAVE seen rounding on the Terrain Y axis and now you are confusing and carrying over your Terrain axis facts onto a belief' that it's the same for Static objects.

An objects Y axis is Never rounded below 4 decimal places. . . . Rounding does occur on Terrain Y axis and is dependent on the Error Bias setting.

Go ahead, try it; set an object to 11.1234 then change it to 11.1233 and see what you get.Look in the W fill too!
Try the same thing with Terrain Y axis and you'll see all sorts of rounding.

I put this easily understandable information in my FIRST response to your off topic 'rounding' injection into the discussion.

He's completely out to lunch if he thinks he should be patted on the back for having an epiphany about thousandths of a meter.

I'm not looking for a 'pat on the back Joe, I was attempting to help a fellow member when you barged in with YOUR theorys. Were you trying to bait me?

I DONT CARE ABOUT ROUNDING! Especially when it only applies to terrain altitude and NOT THE SUBJECT AT HAND; The precision setting of an objects altitude

Vince is right the End key doesn't do anything when moving objects, but then I never actually said it did.Cl

Yeah you did, caught in another lie.

Jean, sorry your thread got tore up a bit. Keep up the good work, and remember to use the End key if you keep tapping.

You owe everyone an apology Sir! Man up!
