本文整理了Java中java.math.BigInteger.not()方法的一些代码示例,展示了BigInteger.not()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台,是从一些精选项目中提取出来的代码,具有较强的参考意义,能在一定程度帮忙到你。BigInteger.not()方法的具体详情如下:
包路径:java.math.BigInteger
类名称:BigInteger
方法名:not

BigInteger.not介绍

[英]Returns a BigInteger whose value is ~this. The result of this operation is -this-1.

Implementation Note: Usage of this method is not recommended as the current implementation is not efficient.
[中]返回一个BigInteger,其值为~this。此操作的结果是-this-1。
实施说明:不建议使用此方法,因为当前的实施效率不高。
