Floating point

Jun 13, 2010 at 1:38 PM

When shapes files are in text format, exponential notation may be used with floating point numbers.


This is currently causing an error.

That number format appears to work fine for me. Do you have an example file that fails to parse such a number? If you've reported the problem through Simis Editor, just let me know the filename and I can check the reports.

Hi James,

If I reported the file the name is AmfleetIICoach4.S

This file can be found at

I have been working with this file as it also has problems with OpenRails,

Ah, the problem isn't the floating point numbers but the use of slerp_rot inside tcb_rot (the error details might not have been entirely clear; it is whatever is labeled "data at failure" that it has a problem with) - the BNFs I've written simply didn't allow that (not seen it used before, probably).

I've commited a new version of shape.bnf which (if copied in to Resources) allows this file to be loaded.
