Oh huh, so it's special-casing anything that starts with a "nan":

$ perl -e 'print "nano" + 1'
nan
$ perl -e 'print "nan1" + 1'
nan
$ perl -e 'print "nan3" + 1'
nan
$ perl -e 'print "nannnnn" + 1'
nan
$ perl -e 'print "nap" + 1'
1
$ perl -e 'print "nan" + 1'
nan
$ perl -e 'print "NAN" + 1'
nan

Probably, yes -- and parsing them as "not-a-number" (NaN). And adding 1 to NaN gives you NaN (a bit like NULLs in SQL).

Heh, yes. Weird!
