[Boost-users] [Graph] float/double weights and brandes_betweenness_centrality

Hi, I wonder whether float/double weights may cause a bug in brandes_betweenness_centrality. In the brandes_dijkstra_visitor, in the case where edge is not relaxed, there is an equality check if (d_w == combine(d_v, w_e)) in order to find if there is equally-short path from v to w. If d_w, d_v, w_e are float/doubles, isn't there gonna be a problem with the "=="? Thanks Ioannis
