bytesToFloat32 static method

double bytesToFloat32(Uint8List bytes, { ByteOrder byteOrder = ByteOrder.bigEndian, })

Convert bytes to 32-bit float (Float32/Single).

Parameters:

• bytes: 4 bytes in big-endian format
• byteOrder: Word order (default: ByteOrder.bigEndian)

Returns: 32-bit floating point number

Example:

final bytes = await client.readHoldingRegistersBytes(1, 100, 2);
final temperature = DataConverter.bytesToFloat32(bytes);
print('Temperature: $temperature °C');

Implementation

static double bytesToFloat32(Uint8List bytes, {ByteOrder byteOrder = ByteOrder.bigEndian}) {
  if (bytes.length < 4) {
    throw ArgumentError('Requires at least 4 bytes for Float32');
  }
  final data = ByteData.sublistView(bytes);
  if (byteOrder == ByteOrder.bigEndian) {
    return data.getFloat32(0, Endian.big);
  } else {
    final high = data.getUint16(2, Endian.big);
    final low = data.getUint16(0, Endian.big);
    final result = ByteData(4);
    result.setUint16(0, high, Endian.big);
    result.setUint16(2, low, Endian.big);
    return result.getFloat32(0, Endian.big);
  }
}
