The user can opt to trade speed of computation for a higher margin of error, but the app can generally get the error under 1 percent in less than a second.

用户可以用更高的误差来换取更快的计算速度，不过这个程序已经能在不到1秒的时间获得小于百分之一的误差。

But it won't be; the computation will continue as if the cast had succeeded, signaling an error further into the computation or worse, completing with corrupt data but no outward signs of trouble.

但并非如此；计算将继续，就仿佛数据类型转换成功了一样，然后在进一步进行计算时发出错误，或者更糟：用遭破坏的数据完成计算，但不向外发出任何错误信号。

This algorithm improves convergence speed and reduces residual error by increasing small the quantity of computation.

该算法通过增加很少的计算量不仅提高了收敛速度而且获得更小的剩余误差。
