Yes, it could.
How about a "farange", designed for floating point values -- I
imagine someone smarter than me about for could write one that would
guarantee that end-point w

One motivation of this thread was that
adding a step parameter to linspace might make
things easier for beginners.
I claim this thread has put the lie to that,
starting with the initial post. So what is the
persuasive case for the change?
Imo, the current situation is good:
use arange if you wan

If I've understood you:
start + stepsize*np.arange(nsteps)

How is that different to arange? Either you specify the number of points
with lins
Hi,
there has been a request on the issue tracker for a step parameter to
linspace. This is of course tricky with the imprecision of floating
point numbers.
As a trade off, I was thinking of a step parameter that is used to
calculate the integer number of steps. However to be certain that it
