title: Looking for .NET Math method that will zero a negative integer
body: <p>Similar in concept to Math.Abs() - I'm looking for a function that when given a positive integer will return the same integer. If given a negative, will return zero.</p>
  
  <p>So: </p>
  
  <pre><code>f(3) = 3
  f(0) = 0
  f(-3) = 0
  </code></pre>
  
  <p>Yes, this is simple enough to write on my own but I'm wondering if the .NET Math class already has this built in or if the same can be achieved by cleverly chaining a few Math.* calls?</p>
