Double.compareTo介绍

[英]Compares this object to the specified double object to determine their relative order. There are two special cases:

• Double.NaN is equal to Double.NaN and it is greater than any other double value, including Double.POSITIVE_INFINITY;
• +0.0d is greater than -0.0d
  [中]将此对象与指定的双对象进行比较，以确定它们的相对顺序。有两种特殊情况：
  *加倍。南等于双。NaN，它大于任何其他双精度值，包括double。正无穷大；
  *+0.0d大于-0.0d
