Is your processor also "little endian"

Yes!
We use entirely refurbished Dell PCs built on Intel processors. This one is:
Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz 3.30 GHz

I would suspect that 64 bit Perl's representation of a simple float is also 64 bits? Added: I see trouble if you are using 32 bit Perl.

It hadn't occurred to me that the Perl build or the processor would affect this decoding but that does make sense. I am running Strawberry Perl:
This is perl 5, version 32, subversion 1 (v5.32.1) built for MSWin32-x64-multi-thread

So, that looks to me like we should be OK there.
