This code is wrong for iota(1.0, 9.5), because .back must be of the form start + n*step for some integer n, but in this case end is not an integral multiple of step away from start. (It's not only wrong for .back, it also won't terminate because start==end will never hold.)
It is a simplified example. It has no pretence of handling floating point.
