python tanh反函数 - CSDN
WebNotes. arctanh is a multivalued function: for each x there are infinitely many numbers z such that tanh (z) = x. The convention is to return the z whose imaginary part lies in [-pi/2, pi/2]. For real-valued input data types, arctanh always returns real output. For each value that cannot be expressed as a real number or infinity, it yields nan ...
