异或Java中的两个双打 [英] XORing two doubles in Java

问题描述

如何在异或JAVA两个双打？

How to XOR two doubles in JAVA?

简单的'^'不双打工作...我将不得不转换为双二进制形式并做到这一点按位？或有任何其他方式？

simple '^' doesn't work for doubles... Would I have to convert a double to binary form and do it bitwise? or is there any other way?

推荐答案

如果你的意思是要做到这一点按位，你需要使用双击实用功能让长重新presentations然后再转换回双重底：

If you mean to do this bitwise you need to use the Double utility functions to get long representations and then convert back to a double at the end:

double c = Double.longBitsToDouble(
    Double.doubleToRawLongBits(a) ^ Double.doubleToRawLongBits(b));
