In thread Extracting IEEE 754 floating point numbers
are two working answers to my problem, that of converting network-order IEEE 754 float values to native float values on an Intel machine. Although one of them
$num = unpack "f", reverse $packed_num;
had occurred to me, the other one
$float = unpack "f", pack "N", unpack "V", $data;
just 'feels' wrong. Before finding that thread I had tried
$float = unpack 'f', pack 'L', unpack 'N', $data;
which also works.
Now the fact is that on the Intel platforms pack 'N', unpack 'V', $data and pack 'L', unpack 'N', $data both accomplish the transformation from big-endian to little-endian byte order.
But it seems to me that I _should_ use 'N' first on the network-order 4-byte value, then force the 4-byte value to a native order 4-byte value, and only then convert to a native float value. In this way the same code would work on non-Intel machines?
I guess I'm asking, which is the more pedant-proof answer?
