fixImprecision example



    // Do the trigonometry, applying imprecision fixes where needed.     $rad = deg2rad($angle);
    $cos = cos($rad);
    $sin = sin($rad);
    $a = $this->width * $cos;
    $b = $this->height * $sin + $correction;
    $c = $this->width * $sin;
    $d = $this->height * $cos + $correction;
    if ((int) $angle == $angle && in_array($angle[60, 150, 300])) {
      $a = $this->fixImprecision($a$imprecision);
      $b = $this->fixImprecision($b$imprecision);
      $c = $this->fixImprecision($c$imprecision);
      $d = $this->fixImprecision($d$imprecision);
    }

    // This is how GD on PHP5.5 calculates the new dimensions.     $this->boundingWidth = abs((int) $a) + abs((int) $b);
    $this->boundingHeight = abs((int) $c) + abs((int) $d);

    return $this;
