Tim Peters <t...@python.org> added the comment:
+0 from me. Another use is computing the Carmichael function for composite numbers (like an RSA encryption modulus, in which context the Carmichael function is routinely used). But only +0 instead of +1 because it's so easy to build from gcd(). I don't agree it's tricky at all. While lcm(0, 0) undoubtedly should return 0 in a general-purpose library function, in my own code I've never supplied that. Because in every application I've ever had for it, I would rather get an exception if I ever passed two zeroes - that would always have been a mistake. ---------- nosy: +tim.peters _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39479> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
