I am trying to generate some binary data on an x86 box (i.e little-endian) that emulates generating that data on a Sun box (i.e. big-endian). I can get most of the integer fields (various byte-lengths) to format correctly using pack. However, I have hit a brick-wall for floating point values (float not double).

I think my problem lies here (from the pack documentation): "f A single-precision float in the native format."

My guess is that the key phrase there is native format.

So, is there a way of generating a float in "non-native" format to look like it comes from a big-endian CPU? I tried simply reversing the bytes, but that didn't work:

reverse pack("f", $floatVal)

Any ideas most welcome!
