Decimals from COMs have trailing zeros

I'm not sure what exactly is causing this, be it mIRC's change to precision or something I've over looked. The best way I can explain it is via example:

Code:

alias example {
  if ($com(bug)) {
    .comclose bug
  }
  comopen bug MSScriptControl.ScriptControl

  if ($comerr || !$com(bug)) {
    echo -a Failed to create com
  }
  elseif (!$com(bug, language, 4, bstr, jscript)) {
    echo -a Failed to set language
  }
  elseif (!$com(bug, ExecuteStatement, 1, bstr, example = 5.7)) {
    echo -a Failed to execute jscript
  }
  elseif (!$com(bug, Eval, 1, bstr, example)) {
    echo -a Failed to eval
  }
  else {
    ;; this returns 5.70000
    echo -a This should be 5.7 :: $com(bug).result
  }

  if ($com(bug)) {
    .comclose bug
  }
}
