As mentioned, with complex numbers the radians make more sense and of course cmath.sind(x) + 1j * cmath.sind(x) != cmath.exp(1j * x).
However, adding degrees version for cmath (import cmath) is still useful, cmath.rectd, cmath.phased, cmath.polard etc. 2018-06-11 19:24 GMT+02:00 Michael Selik <m...@selik.org<mailto:m...@selik.org>>: Would sind and cosd make Euler's formula work correctly? sind(x) + i * sind(x) == math.e ** (i * x) I suspect that adding these functions is kind of like those cartoons where the boat is springing leaks and the character tried to plug them with their fingers. Floating point is a leaky abstraction. Perhaps you'd prefer an enhancement to the fractions module that provides real (not float) math? _______________________________________________ Python-ideas mailing list Python-ideas@python.org<mailto:Python-ideas@python.org> https://mail.python.org/mailman/listinfo/python-ideas Code of Conduct: http://python.org/psf/codeofconduct/
