I have discovered the hard way, 'pack/unpack' functions for 64 bit do not operate on 32 bit machines.

I thought I'd covered that with "and (may) only support 32-bit integers.".

I was trying to put a floating point number into a "Q" format (64bit integer) but on the 32 bit machine it threw an exception.

Putting a floating point number into an integer makes no sense to me at all?

I'm surprised you got an "exception". If I try to use 'Q' on my 32-bit installation, it simply tells me that it is invalid:

c:\test>\perl32\bin\perl -wle"print pack 'Q', -1"
Invalid type 'Q' in pack at -e line 1.

c:\test>\perl32\bin\perl -wle"print unpack 'Q', 'abcdefghijklmnop'"
Invalid type 'Q' in unpack at -e line 1.
