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

 } else if (d1 == null)
  return 0; // both are null
 return d1.compareTo(d2); // natural ordering.
}
