float32ToBytes static method

Uint8List float32ToBytes(double value, { ByteOrder byteOrder = ByteOrder.bigEndian, })

Convert 32-bit float to bytes.

Parameters:

• value: 32-bit floating point number
• byteOrder: Word order (default: ByteOrder.bigEndian)

Returns: 4 bytes in big-endian format

Example:

final setpoint = 25.5;
final bytes = DataConverter.float32ToBytes(setpoint);
await client.writeMultipleRegistersBytes(1, 200, 2, bytes);

Implementation

static Uint8List float32ToBytes(double value, {ByteOrder byteOrder = ByteOrder.bigEndian}) {
  final data = ByteData(4);
  if (byteOrder == ByteOrder.bigEndian) {
    data.setFloat32(0, value, Endian.big);
  } else {
    data.setFloat32(0, value, Endian.big);
    final high = data.getUint16(0, Endian.big);
    final low = data.getUint16(2, Endian.big);
    data.setUint16(0, low, Endian.big);
    data.setUint16(2, high, Endian.big);
  }
  return data.buffer.asUint8List();
}
