title: Gfortran warning: change of value in conversion from REAL(8) to INTEGER(4)!
body: <p>I'm using an old fortran script (accessible <a href="https://drive.google.com/file/d/0B6GUNg-8d30vRnhpaDlsUmgwLXM/view?usp=sharing" rel="nofollow noreferrer">here</a>). I'm receiving the following warnings (line#192, 233-235). Is there a way to fix it? I'm using <em>gfortran 6</em> on my mac.</p>
