Hello Jeremiah ! Indeed, I defined it using int and hence double were converted! Thanks a lot for the help! Kind regards Jen Buysse Op 20/07/2011 2:52, Jeremiah Willcock schreef:

Dear all,
I'm new to the BOOST library (and actually also to c++).
I have the following problem: I want to use the dijkstra algorithm for computing shortest paths in a network. For this I calculate weights, which in my case take the form of double < 1. But it seems internally boost converts to an integer. Is there a way to use double without miltilplying it with e.g. 100 to get Integers?
The code uses whichever data type your graph and property maps use to store the edge lengths. Does your distance map have a value type of double? That is what is used to determine the type used internally for lengths and distances.
