本文整理了Java中java.io.DataOutputStream.writeDouble()方法的一些代码示例，展示了DataOutputStream.writeDouble()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。DataOutputStream.writeDouble()方法的具体详情如下：
包路径：java.io.DataOutputStream
类名称：DataOutputStream
方法名：writeDouble

DataOutputStream.writeDouble介绍

[英]Converts the double argument to a long using the doubleToLongBits method in class Double, and then writes that long value to the underlying output stream as an 8-byte quantity, high byte first. If no exception is thrown, the counter written is incremented by 8.
[中]使用类Double中的doubleToLongBits方法将双参数转换为long，然后将long值作为8字节量写入基础输出流，先高字节。如果未引发异常，计数器written将递增8。
