It provides access to mathematical -functions for complex numbers. The functions are: +functions for complex numbers. The functions in this module accept +integers, floating-point numbers or complex numbers as arguments. +They will also accept any Python object that has either a +\method{__complex__} or a \method{__float__} method: these methods are +used to convert the object to a complex or floating-point number, respectively, and +the function is then applied to the result of the conversion. + +The functions are: \begin{funcdesc}{acos}{x} Return the arc cosine of \var{x}. |
