Julian, That seems like a very reasonable request since it is a common problem. Here is one approach. Write a routine that converts an "iterator" defined in terms of the number of points into a normal iterator. pointsiter[i_, min_, max_, numpoints_] := {i, min, max, (max - min)/(numpoints - 1)} Table[i, pointsiter[i, 2, 15, 6] // Evaluate] {2, 23/5, 36/5, 49/5, 62/5, 15} Table[i, pointsiter[i, -0.235, 2.654, 5] // Evaluate] {-0.235, 0.48725, 1.2095, 1.93175, 2.654} I don't know how to eliminate the need for Evaluate without changing the Attributes of Table. Also with floating point values I am not certain if Mathematica will always get the last point.
