I have an arithmetic expression template where multiplication is commutative. Is there an easy way to order a chain of multiplications such that terminals with values (like proto::terminal< double >) appear at the beginning? For example that
arg1 * arg1 * 1.5 * arg1 will be transformed to 1.5 * arg1 * arg1 * arg1 ? I can imagine some complicated algorithms swapping expressions and child expressions but I wonder if there is a simpler way. _______________________________________________ proto mailing list proto@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/proto
