  Re: number notation in official parts
 
(...) Thanks for the info. I've always used perl scripts to convert oddly formatted data to a consistent format and then read it like that. Nice to know I don't always have to. If it could only read some of the more bizarre Fortran formats I'd never (...) (14 years ago, 12-Mar-10, to lugnet.cad.dev, lugnet.off-topic.geek)
 
  Re: number notation in official parts
 
(...) All float specifiers (e, E, f, g, G) are treated identically by the scanf functions. When scanning floats, they always recognize all float formats. One other thing about %g on output is that it automatically strips trailing zeros, which %f (...) (14 years ago, 12-Mar-10, to lugnet.cad.dev)
 
  Re: number notation in official parts
 
(...) Ahhh. I'd never heard of %g before now. I'm so used to %f and %e it had never occured to me that there might be a mixed option. Handy to know as I suspect it would be helpful in reading files of unknown format. I'm sure Delphi has some hideous (...) (14 years ago, 12-Mar-10, to lugnet.cad.dev)
 
  Re: number notation in official parts
 
(...) Actually, in C, %g does exactly this. Having said that, I think LDDP is a Delphi app, so it uses Pascal, and I don't remember how Pascal does formatting. --Travis (14 years ago, 12-Mar-10, to lugnet.cad.dev)
 
  Re: number notation in official parts
 
(...) I definitely know this. I see them far too much in my job as a numerical physicist ;) My point is that to write in mixed format (some %f and others %e) requires some strange coding unless there is a weird language which does it automatically.

  Re: number notation in official parts
 
(...) Hmm, I thought I killed that "feature". I'll look into it as I find time to finish up LDDP 2.1 -Orion (14 years ago, 11-Mar-10, to lugnet.cad.dev)
 
  Re: number notation in official parts
 
(...) I mostly agree with this policy. (...) There is nothing strange in the routines, it is the standard format used to represent very large or very small numbers in a limited number of digits. Actually since values never get very large in LDraw (...) (14 years ago, 11-Mar-10, to lugnet.cad.dev)
 
  Re: number notation in official parts
 
(...) My suggestion would be to read numbers in that notation but never write them. I'm not sure why LDDP would write them that way (it would require some strange output routines) but if one thing writes them then it's best to read them. Tim (14 years ago, 11-Mar-10, to lugnet.cad.dev)
 
  Re: number notation in official parts
 
(...) I think it should be forbidden in official files as the benefit is very small and it is not good human readable. Benefit would be smaller filesize, as 0.0004 (6 characters) has more characters than 4E-4 (4 characters). Against could be 0.4 (3 (...) (14 years ago, 10-Mar-10, to lugnet.cad.dev)
 
  Re: number notation in official parts
 
(...) Such notation is not noted in any specs.. neither allowed or forbidden. At least, I can't find such. Maybe we should bring this up at LSC at some point? (FWIW I sent this in yesterday but it seems the server ate the message.. resending it) (...) (14 years ago, 9-Mar-10, to lugnet.cad.dev)

  number notation in official parts
 
If I rotate a part in LDDP the result may look like this: 1 16 4E-15 4 -20 0 0 1 0 -1 0 -1 0 0 stud4.dat This can be read by LDView and MLCad as a valid number. Is such notation allowed in official parts? It is nowhere explicit allowed or (...) (14 years ago, 8-Mar-10, to lugnet.cad.dev)
 
  LDSwitch Sample #1: Do/Undo  [DAT]
 
Don't know if you prefer to make input here or at SourceForge, so I crosspost. Please give feedback where you like, here or at SF. Here's the first sample LDraw code snippet. Set the value of the variable Rev028_Changes to Do or Undo, run the (...) (14 years ago, 23-Feb-10, to lugnet.cad.dev)
 
  LDSwitch Project on SourceForge
 
(...) I've just registered myself and my first project at SourceForge: (URL) to join or just input! /Tore (14 years ago, 23-Feb-10, to lugnet.cad.dev)
 
  LDSwitch?
 
Is the name/keyword/META-command LDSwitch/!LDSWITCH free to use or is it taken? I think it's not taken (in the LCad context), so I wish to claim it if noone protests. /Tore (14 years ago, 23-Feb-10, to lugnet.cad.dev)
 
  Re: Undo/Redo Information META Tags? Or Options Buttons?
 
(...) And I'm not sure this would be the optimal solution either. This options thing is more like a case switch than a series of if statements. (...) Thanks for your input, Kevin. I am looking for a friendly solution that won't output any code that (...) (14 years ago, 19-Feb-10, to lugnet.cad.dev)
 
  Re: Undo/Redo Information META Tags? Or Options Buttons?  [DAT]
 
(...) Well, you could easily do the above using the C preprocessor and #ifdefs, but that would be outside any LCAD application (and make the original file hard to work with in any modeler). #ifdef LDBOXTER_LEVEL_D /* crude simplification */ 1 15 0 (...)

  Undo/Redo Information META Tags? Or Options Buttons?  [DAT]
 
I've been thinking hoe nice it would be if there was some kind of system of tags that enabled the user to store undo and redo information in a model after the model building application is closed. Now, there are a great number of LCAD apps of which (...) (14 years ago, 19-Feb-10, to lugnet.cad.dev)
 
  Defining LED Colors in LDConfig?
 
I've been thinking about that talk of limiting the colour definitions in LDConfig.ldr to part colours with a few expectations, and I agree with that. But I wish to throw in an idea that I don't even believe in myself but yet want to air. Is it (...) (14 years ago, 10-Feb-10, to lugnet.cad.dev)
 
  Re: LDraw Names for Monorail Parts
 
(...) It makes more sense for "Monorail" to be a valid CATEGORY than some of the existing ones, so I added it a while ago. The definitive list is at (URL) Chris (14 years ago, 21-Jan-10, to lugnet.cad.dev, lugnet.trains)
