Well, in Matlab the end point is specified and the result of the division is probably rounded, so in order to have problems you might need to use something like .55 as the endpoint. In Numpy's arange an upper bound is used instead, so roundoff is a problem, but the 5.5 case would be handled easily. Chuck
