title: Get range count between low and high with step
body: <p>This might be a stupid question, but I'm drawing a blank. I'm looking to get the max possible numbers/instances between a low and high number with step.</p>
  <p>For example, given this dictionary:</p>
  <pre><code>dictionary_one = {&quot;low&quot;: -2.0, &quot;high&quot;: 2.0, &quot;step&quot;: 0.1}
  </code></pre>
  <p>... I want this output</p>
  <pre><code>41
  </code></pre>
  <p>... as that is the total of all possible combinations between that range (i.e. -2.0, -1.9, -1.8, ..., 1.8, 1.9, 2.0). The low and high should be inclusive.</p>
  <p>Preferably without using a for loop for the count, but whatever works. Thanks!</p>
