For n=5, the result is right.

But for n=6, it's supposed to have 7 elements instead of 6

Wrong way to discretize a range.

Probably something about precision of double type. In the second range if you add a 10^-14 to the uppper bound it return the expected vector.

n even starts being exact ... n 10
n odd stops being exact ..... n 15
You have no control on numerical arithmetic.
