No.

$ perl -wle'print "0 but true" eq "0E0" ?1:0'
0

They are both silently equal to zero yet true, but so are the other poll options (except "0x0").

$ perl -wle'print 0+"0 but true"'
0

$ perl -wle'print 0+"0E0"'
0

$ perl -wle'print "0 but true" ?"true":"false"'
true

$ perl -wle'print "0E0" ?"true":"false"'
true
