你遇到过的源代码中最好的注释是什么?


当前回答

我在查看TVNZ网站早期迭代的HTML源代码时发现了这个宝藏(如果你在家玩的话,从571行开始):

<!-- Hopfully we can do this otherwise the nav is going to be pretty plain and Hong will go postal. -->

//I am not sure why this works but it fixes the problem. 

这是之前的一组代码,技术上确实解决了问题,它的意思是,但打破了其他3个东西....

// Magic. Do not touch.

//把这个放在这里的人是个白痴…这根本不管用!

但是代码还在那里……

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;
}
