title: Javascript Math Object Methods - negatives to zero
body: <p>in Javascript I can't seem to find a method to set negatives to zero?</p>
  
  <p>-90 becomes 0<br />
  -45 becomes 0<br />
  0 becomes 0<br />
  90 becomes 90<br /></p>
  
  <p>Is there anything like that? I have just rounded numbers.</p>
