title: what is the purpose of double implying?
body: <p>for example:</p>
  
  <pre><code>const decimal dollars = 25.50M;
  </code></pre>
  
  <p>why do we have to add that <code>M</code>?</p>
  
  <p>why not just do:</p>
  
  <pre><code>const decimal dollars = 25.50;
  </code></pre>
  
  <p>since it already says <code>decimal</code>, doesnt it imply that <code>25.50</code> is a decimal?</p>
