Mark Dickinson <dicki...@gmail.com> added the comment: Python's result looks fine to me, as does numpy's: they're both giving a valid inverse hyperbolic sine:
>>> from cmath import sinh >>> sinh(1.3169578969248166-1.5707963267948966j) (1.0605752387249067e-16-1.9999999999999998j) >>> sinh(-1.3169578969248164-1.5707963267948966j) (-1.0605752387249064e-16-1.9999999999999993j) Perhaps numpy is using different branch cuts? ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue1381> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
