I'm aware that efforts to agree on a units library have failed to reach a consensus. But perhaps its might be possible that a consensus could be reached on a dimensional analysis library? That would be a good first step and useful in its own right.
Yes the dimensional analysis is in practise simple and well known , (due to Walter Brown, David Abrahams/AlexeiGurtovoys et al's code) and could presumably be finalised, but it needs implementation of a compile time rational eg boost::mpl::rational_c ( I think Cromwell Enage is working on this?), (with some compiletime operators.),which is a 'building block' for it. I assume that the rational impl could then plug straight in to the mpl book code ? regards Andy Little
