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

DataOutputStream.writeFloat介绍

[英]Converts the float argument to an int using the floatToIntBits method in class Float, and then writes that int value to the underlying output stream as a 4-byte quantity, high byte first. If no exception is thrown, the counter written is incremented by 4.
[中]使用类Float中的floatToIntBits方法将浮点参数转换为int，然后将int值作为4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4。
