Hello! Playing with JacobiAmplitude after reading [mg23882], I have found something strange with the numerical evaluation of JacobiAmplitude: JacobiAmplitude[0, 10^(-17)] gives 0, JacobiAmplitude[1.*10^(-100), 10^(-17)] gives 1.*^-100, while JacobiAmplitude[0., 10^(-17)] gives a string of error messages and a funny output. My version is "4.0 for Power Macintosh (May 9, 1999)" Bye, Gianluca Gorni -- +---------------------------------+ | Gianluca Gorni | | Universita` di Udine | | Dipartimento di Matematica | | e Informatica | | via delle Scienze 208 | | I-33100 Udine UD | | Italy | +---------------------------------+ | Ph.: (39) 0432-558422 | | Fax: (39) 0432-558499 | | mailto:gorni at dimi.uniud.it | | http://www.dimi.uniud.it/~gorni | +---------------------------------+
