I expected something akin to what every decent tool out there produces:
$ ruby -e "puts (72/2.54)*2.54" 72.0
$ php -r "echo((72/2.54)*2.54);" 72
$ perl -e "print ((72/2.54)*2.54)" 72
heck, even JavaScript gets it right...
Funnily enough, the "Send Line to Google Calculator" on the same bundle gets it right...
