If you mean that you want to show the byte representation in hex of each float value in the array then try this. There are of course 4 bytes in a float value in C#: using System; class Program { static void Main() { float[] floats = {0f 1.2f 2.34F 3.456f}; foreach(float f in floats) { byte[] bytes = BitConverter.GetBytes(f); string hex = BitConverter.ToString(bytes); Console.WriteLine(The hex bytes of {0:F3} are {1} f hex); } Console.ReadKey(); } } The output (assuming a little-endian architecture such as x86) is: The hex bytes of 0.000 are 00-00-00-00 The hex bytes of 1.200 are 9A-99-99-3F The hex bytes of 2.340 are 8F-C2-15-40 The hex bytes of 3.456 are 1B-2F-5D-40
