title: Rounding Down to nearest whole number - am I cheating or is this more than adequate?
body: <p>Essentially, if the number generated is 2.3 then if I subtract .5 it will then be 1.8 but the rounding function will make it 2, which is what I want. Or if the answer is 2.99999 and I subtract .5, the answer is 2.49999 which should round down to 2 which is what I want. My question is if the answer is 2 even and I subtract .5, the answer is now 1.5, so will it still round up to 2. </p>
  
  <pre><code>temp1_1= Math.round(temp2_2/(360/temp_value)-.5);
  </code></pre>
  
  <p>this is my line of code for this.</p>
