C# float to byte array
WebOct 26, 2024 · 1 Answer. Under the covers, it is using unsafe, C-style pointers to copy the underlying 32-bit value into a 32-bit array (a byte [4] ): int rawBits = * (int*)&value; byte [] bytes = new byte [4]; fixed (byte* b = bytes) * ( (int*)b) = rawBits; return bytes; The results are architecture dependent, insofar as the order of the bytes matches the ... WebJun 27, 2012 · A byte uses exactly a byte in memory, but a float uses 4 bytes (32 bits). If you don't have the memory requirements to store your data, just represent the data as the data type you will be using the most in memory, and convert the values you actually use, when you use them.
