endianness

问题 I am trying to write an Integer from C# and read it from Java. An integer is 4 bytes in both languages. However when I write it from C#, integer 1 is written in the following bytes 1000. Meaning the first byte is 1 and the rest is 0. But in Java the same thing is written as 0001. Meaing the first 3 bytes are 0 and the last is 1. Is there a simple way of reading and writing among these languages instead of manually reversing every 4 byte? The code for Java ByteBuffer buffer = ByteBuffer

问题 I have a Hex String which reads 18000000 this String is in Host byte order (Little endian) and I need to convert it to Network byte order (Big endian). The resultant Hex String will be 00000018 . To summarize I need to convert 18000000 to 00000018 How do I achieve this in PHP? 回答1: You can use pack / unpack functions to convert endianness: /** * Convert $endian hex string to specified $format * * @param string $endian Endian HEX string * @param string $format Endian format: 'N' - big endian,

问题 Double is represented in memory using 8 bytes. I believe these 8 bytes should be having two components, one each for integer-part and one for the fractional-part(Correct me if I am wrong in this assumption). My machine is a little endian(Nowadays every Macmini is). I want to transfer these 8 bytes representing Double to a file, which should be readable on a BigEndian platform(Specifically JVM which is BE). It is safe for plain Integers to reverse the byte order, as they don't have components

问题 I am trying to build an Android app that records PCM audio and exports it as a wav file. It worked fine for 8BitPCM, but when I switched to 16BitPCM I got white noise. I finally figured out it was the endianness of the byte array, but now, after converting from Little Endian to Big Endian, I get my audio crystal clear, but reversed! Here is how I call the method: byte[] inputByteArray = convertLittleEndianToBig(readToByte(input)); and then that byte[] is appended to my .wav header here:
