恩,累加得,乘2PI再除得都试了,我写了4个算法呢..就是差0.001,可能是因为我求圆心用了一次COS吧,

In Reply To:这个误差就很小了嘛，关键就看你怎么算角度了，不要用累加的，每次都2PI乘一下再除 Posted by:frkstyc at 2005-07-20 22:41:33

关键就是,你的算法必须和它一模一样.这太恶心了 (0) uni 2005-07-21 00:01:20
呵呵，最不该用的地方用了，你就等着被E吧 (0) c0500448264 2005-07-21 00:01:37
- 恩。.只是一次而已,而且剩下的精度绝对没问题,我就是不能忍了.这TMD也太E了,呼吁以后比赛计算几何全都有SPJ,杜绝0.001现象出现 (0) uni 2005-07-21 00:05:46
  - 正式比赛就不定有了，现在碰钉子当是积攒rp吧 (0) frkstyc 2005-07-21 00:07:18
