/* Project : XYZ (Please somebody shoot me!)

 * File : $Id: defs.h,v 1.1 $
 *
 * Purpose : Create havoc rather than peace among many nations
 *
 * History : Back-ported changes that were not in CVS.  Please somebody,
 *  shoot us and put us all out of our misery.

“XYZ项目”(已改名)是一个长达七年的折磨。最后这句话是由一个从头到尾都参与其中的坚定的灵魂写的。

以下是4个，排名不分先后:

// Father, forgive me, for I am sinning

// heaven help me

// horse string-length into correctitude 
(from a textbook)

// what, me worry?

消毒:

//Forward declarations:

class X {}; // TODO: Remove {}  ! When we get X defined....

// Caveat implementor

// I am not sure if we need this, but too scared to delete. 

从《雷神之锤III》的资料中，我在一些随机的帖子中偶然发现了这一点。该文件的完整源代码可以在这里找到。这是一种非常快速的求平方根倒数的方法。至于最好的评论呢?当然，这是一种常见的方法，但考虑到它附着在直线上，它的神奇之处在于它的伟大之处。

float Q_rsqrt( float number )
{
  long i;
  float x2, y;
  const float threehalfs = 1.5F;

  x2 = number * 0.5F;
  y  = number;
  i  = * ( long * ) &y;  // evil floating point bit level hacking
  i  = 0x5f3759df - ( i >> 1 ); // what the fuck?
  y  = * ( float * ) &i;
  y  = y * ( threehalfs - ( x2 * y * y ) ); // 1st iteration
  // y  = y * ( threehalfs - ( x2 * y * y ) ); // 2nd iteration, this can be removed

  #ifndef Q3_VM
  #ifdef __linux__
    assert( !isnan(y) ); // bk010122 - FPE?
  #endif
  #endif
  return y;
}
