Re: [graph-tool] returning arrays from shortest_distance method -> positive infinity numbers

I am using the shortest_distance method with a starting point vertex and a maximum search distance. When returning the results, the vertices outside of the maximum distance threshold are returned as maximum 64bit float numbers (1.79769313486e+308), presumably converted from Numpy’s internal positive infinity value. Is there a way to return the array with numpy’s positive infinity value intact so that I can use the numpy.isposinf method to directly convert the array into a boolean format which I can then use for masking the graph? Thanks.
