create QByteArray::fromRawData with float getting unexpected results

[kain]

Hey there,

I have some question about a problem I just encountered. I am using QByteArray::fromRawData to send data via QSerialPort.
This works fine for most of my data (some structs) but right now I am experiencing some results I can not explain:
for example the call

float myfloat = 500;
auto tmp = QByteArray::fromRawData(reinterpret_cast<const char*>(&myfloat), sizeof(float));

results in 0xc0d8001f
instead of 0x43fa0000 as I would expect ( https://gregstoll.com/~gregstoll/floattohex/ )

Does anyone know the reason for that and how I can get my result to work as expected? I am using this method call in a template to encode arbitrary data:

auto sendBuffer = QByteArray::fromRawData(reinterpret_cast<const char*>(&sendItem), sizeof(T1));

Thanks,

@kain looks pretty sane, if you don't care for endianess.

But note that fromRawData does not copy, so the float must stay in scope until the data is sent.

That solved indeed my problem! Thanks!
