title: How to change the rounding mode for floating point operations in MATLAB?
body: <p>I want to change the rounding mode for floating point operations in MATLAB. According to IEEE 754-2008, there are 5 strategies for rounding:</p>
  
  <ul>
  <li>round to nearest, ties to even</li>
  <li>round to nearest, ties away from zero</li>
  <li>round toward zero</li>
  <li>round up (toward positive infinity)</li>
  <li>round down (toward negative infinity)</li>
  </ul>
  
  <p>Does MATLAB supports these 5 strategies? How to change the rounding mode for floating point operations in MATLAB?</p>
