                            經常看到靜態擴展使用 math 庫。這個代碼展示一個簡單的例子：

~~~
class MathStaticExtension {
  /* Converts an angle in radians to degrees */
  inline public static function toDegrees(radians:Float):Float {
    return radians * 180 / Math.PI;
  }
}
~~~

~~~
using MathStaticExtension;

class Main {
  public static function main() {
    var ang = 1/2*Math.PI;
    trace(ang.toDegrees()); //90
  }
}
~~~
                    
                
        
                
            
        
                
    
                
    
                
        
                
    
                

                







                  <ruby id="bdb3f"></ruby>
                  <p id="bdb3f"><cite id="bdb3f"></cite></p>
