memcpy to a char buffer, byte swap.
DO NOT reload the swapped float or double into a va
In this case such casting must be done only through pointers, otherwise
you'll just round the floating point number to some (direction dependens on
the system and its configuration) integer.

I'll plat the naive one here. What is the proper Qt API to byte swap a float or
double? create a union? or some other such trick like that?

To be a little be more verbose, here is what the doc says for these
functions:
*Note:* Template type T can either be a qint16, qint32 or qint64. Other
types of integers, e.g., qlong, are not applicable.

I have some code that needs to convert from the system to Big Endian byte
order. All my integers work just fine but I am getting linker errors when
trying to byte swap floats and doubles.
I have #include
and I have a templates function like this:
template
void foo(T value)
{
value = qToBigE
