The biggest issue is agreeing on fixed vs. floating precision.
If it's going to be a template library why not both?
I personally need fixed-point but I can easily see situations where using floating-point would be beneficial.
The floating point has high resolution near zero and very low resolution
at high values. My worry is that once you start moving, creating, intersecting shapes/lines at high values, you may not have a floating point value available for that coordinate. Then you snap to nearest, in which case your parallels are not parallel any more, your collinears are not collinear any more, etc. There are many problems with floating points. Maybe infinite precision, maybe rational numbers will work. I'm sure some of the readers of this thread have more experience with that regards Gyuszi
Ok, but then again, there are also problems with fixed point. So, again, why does the library have to choose and not the user, since we have templates? Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
