toBytes method

(List<int>, FloatLength) toBytes(FloatLength? decodFloatType, { Endian? endianness, bool allowFloat16 = true, })

Encode the floating-point value into a byte representation using the specified floating-point format. Returns a tuple containing the encoded bytes and the format used.

Implementation

  FloatLength? decodFloatType, {
  Endian? endianness,

    } else if (isLessThan32) {
      return (_encodeFloat32(endianness), FloatLength.bytes32);
    }
    return (_encodeFloat64(endianness), FloatLength.bytes64);
  }
  final List<int> bytes;
  switch (decodFloatType) {
    case FloatLength.bytes16:
      if (!isLessThan16) {
        throw CborException("Float value is larger that float 16.");
      }
      bytes = _encodeFloat16(endianness);
      break;
    case FloatLength.bytes32:
      if (!isLessThan32) {
        throw CborException("Float value is larger that float 32.");
      }
      bytes = _encodeFloat32(endianness);
