    Hi,<br>
    <br>
    You can report it as a bug. It is a MacOS only issue because b1
    value is the same as in Scilab 4.1 under Linux and Windows.<br>
    <br>

      <div>Hi!</div>
      <div>I am having problems with the macro eqiir in scilab 5.4 on
        MacOS. I have traced it down to the call to syredi, which is a
        fortran function. When run the example from the help file I get
        different results from scilab 5.4 and scilab 4.</div>

[fact,b2,b1,b0,c1,c0,zzeros,zpoles]=syredi(1,4,[2*%pi/10,4*%pi/10,0,0],0.02,0.001);

      <div>The poles end up correct, but the zeros are rounded or casted
        to int or something like that.</div>
      <div><br>
      </div>
      <div>Does anyone know anything about this? Should I report it as a
        bug?</div>
      <div><br>
      </div>
      <div>This turns out to break a lot of code for me, but in a very
        non-obvious way.</div>
