Public bug reported:
Binary package hint: bsdgames
Yesterday I reported that primes on my hardware yields values beyond the
documented range. The man page claims:
DIAGNOSTICS
Out of range or invalid input results in an appropriate error message
being written to standard error.
I doubt that it's a security vulnerability since primes isn't on the
live CD.
Thus this should result in an error message. Instead primes returns a
composite number.
$ primes 7757777773 7757777787
7757777777
In j notation, q: is the factor verb and */ means "insert multiply".
The precedence rule for sequences of nouns and verbs is simply right to
left evaluation.
q:7757777777x
65827 117851
*/q:7757777777x
7757777777
(Or you could try Factor[7757777777] at Wolfram Alpha, or use a
calculator.)
