《Deep Learning》(Ian Goodfellow & Yoshua Bengio & Aaron Courville)第四章「数值计算」中,谈到了上溢出(overflow)和下溢出(underflow...『1』什么是下溢出(underflow)和上溢出(overflow) 实数在计算机内用二进制表示,所以不是一个精确值,当数值过小的时候,被四舍五入为0,这就是下溢出。

实现思路: 1、彻底禁用MIC,这可以通过MIC的关闭命令来实现,比方tinymix; 但是会有下面的日志输出,表示一直没有MIC数据; 11:30:27.157 Master/sound Underflow..., buf_cnt=0, will generate 1 frame 11:30:27.177 Master/sound Underflow, buf_cnt=0, will generate 1...frame 11:30:27.198 Master/sound Underflow, buf_cnt=0, will generate 1 frame 2、修改PJSIP,实现MIC静音功能。..., buf_cnt=0, will generate 1 frame 11:30:27.177 Master/sound Underflow, buf_cnt=0, will generate 1...frame 11:30:27.198 Master/sound Underflow, buf_cnt=0, will generate 1 frame audio部分的代码一直没有细看,主要是pjsip

Webkit使用的是overflowchanged事件,而Firefox则使用overflow和underflow这两个事件。...虽然Webkit只提供了一个事件,但是我们可以通过event对象的属性来知道是overflow还是underflow,甚至知道是垂直方向还是水平方向。...document.body.appendChild(element); var overflowSupport = false; // firefox(tested on 1.5+) support overflow/underflow

如果一个non-root node的填充度不够,我们就说该node underflow,在B+树里只有root node可以underflow。 这里有一个不合格的B+数的例子。...它不像AVL的insert操作那样简单,B+树还需要考虑node的overflow和underflow。...由于分配之前target node是满的,那么就可以断定分配之后,这两个node不会存在underflow。...在delete的算法中会通过merge(合并)node,去避免underflow。
