Indeed.

He could even use 2 x 32-bit ints as an intermediary for a double:

($lo, $hi) = unpack 'NN', pack 'd', 3.14159265358979;;

print $lo, $hi;;
288179284 4213246272

print unpack 'd', pack 'NN', 288179284, 4213246272;;

Or even 4 x 16-bit ints:

( $_0, $_1, $_2, $_3 ) = unpack 'n*', pack 'd', exp(1);;

print unpack 'd', pack 'n*', $_0, $_1, $_2, $_3;;
