[IMP-dev] Vector 3D in a double precision?

[Seung Joong Kim <>]

I have another question with regard to maintaining double precision.

Currently all vector related classes are defined on the basis of float 
data type (single-precision), so I'm losing accuracy whenever I use 
double data type in a Vector3D class.

Do you have any update plan to implement Vector3D class in a double 
precision?  I think it should be very useful for higher accuracy.

Many Thanks!
