    - #### encodeFloat

          public static byte[] encodeFloat(float payload,
                                           byte[] data,
                                           int offset)

    - #### encodeInt

          public static byte[] encodeInt(int payload)

    - #### encodeInt

          public static byte[] encodeInt(int payload,
                                         byte[] data,
                                         int offset)

    - #### decodeFloat

          public static float decodeFloat(byte[] bytes)

      Returns:
        the decoded float
      See Also:
        `decodeFloat(byte[], int)`, `encodeFloat(float)`

    - #### decodeFloat

          public static final float decodeFloat(byte[] bytes,
                                                int offset)

      Decode the payload that was encoded using `encodeFloat(float)`. NOTE: the length of the array must be at least offset + 4 long.
      Parameters:
        `bytes` - The bytes to decode
        `offset` - The offset into the array.
      Returns:
        The float that was encoded
      See Also:
        `encodeFloat(float)`

    - #### decodeInt

          public static final int decodeInt(byte[] bytes,
                                            int offset)
