Generator.magnitude介绍

[英]Gives a hint to the shrinking process as to the magnitude of the given value. The shrinking process will prefer trying values of greater magnitude before values of lesser magnitude. If not overridden, this implementation returns "one".

Note to generator writers: Do not worry about normalizing a magnitude to a positive value; the shrinking mechanism will take care of it.
[中]就给定值的大小给出收缩过程的提示。收缩过程将倾向于在较小值之前尝试较大值。如果未被覆盖，此实现将返回“一”。
*生成器编写者注意：*不要担心将幅值规格化为正值；收缩机制将处理它。
