title: fortran intrinsic function sqrt() behaviour
body: <p>I have a scenario where i'm trying to execute a complex application on AIX and Linux.</p>
  
  <p>During the execution the code makes use of the intrinsic function sqrt() for computation, but the result obtained is different on both the machines. </p>
  
  <p>Does anyone know the reason for this behavior? Is there anyway to overcome this?</p>
  
  <p>P.S</p>
  
  <p>Some values are equal on both machines but majority of them are different.</p>
