Ooop, you're quite right. Perhaps perldata shouldn't mention strtod as a way to check for numerical-ness then. Of course if you're getting hex numbers as strings you're going to need to convert them (through POSIX::strtod or hex) anyhow before they're interpreted as the correct value so maybe it's kind of a corner case. Good point though.
