<p>If a provided time-step <span class="math inline">\(\Delta
t_{i}\)</span> does not divide the correspond time-difference <span class="math inline">\(t_{i+1}-t_{i}\)</span> in the data then it is
rounded down such that it does. Consider the following example where the
time-difference between two observations in the data is 3 seconds, but a
time-step of 0.7. This produces a non-integer number of steps i.e.:
<span class="math display">\[
N_{i} = \dfrac{t_{i+1}-t_{i}}{\Delta t_i} = \dfrac{3}{0.7} = 4.28...
