Float, Double, to bytes?

[Florian]

I am currently using this way to cast a double or float to an array of bytes (uint8_t) and back:

To bytes:

double data = 5.5;

std::queue<uint8_t> ndata;
uint8_t* tmp = (uint8_t*)&data;
    
for (int i = 0; i < sizeof(double); i++)
    ndata.push(tmp[i]);
    
return ndata;

And back:

double data = 0.0;

std::queue<uint8_t> ndata;
uint8_t* tmp = (uint8_t*)&data;

for (int i = 0; i < sizeof(double); i++)
    tmp[i] = ndata.front(), ndata.pop();

return ndata;

This is butt ugly code though, is there any other way to do this properly in a C++ way (or with Boost)? The resulting bytes will be eventually sent over a network connection (loopback interface actually).

I am working with GCC on Linux x64.
