Hello bearophile,

Why not, define the behavior and leave it.
This was the original purpose of my thread, but Walter has explained
me that this is not possible for the unions:
I don't see how those apply to unions.
It's going to be implementation defined behaviour (will depend on
endianness)
Does that matter if the members are the same size?
Definitely -- you'll grab the part of the mantissa, instead of the exponent.
It should however only be hardware-and-OS-dependent, rather than
compiler-dependent.
(It can be OS-dependent because of different padding rules).
but not undefined behaviour.
BTW std.math heavily relies on reinterpret casting float->int.
