numpy.real_if_close() function - Python Last Updated : 11 Jun, 2020 Comments Improve Suggest changes Like Article Like Report In this numpy.real_if_close()function, if complex input returns a real array then complex parts are close to zero. Syntax : numpy.real_if_close(arr, tol = 100) Parameters : arr : [array_like] Input array. tol : [float] “Close to zero” is defined as tol. Tolerance in machine epsilons for the complex part of the elements in the array. Return : [ndarray] If arr is real, the type of arr is used for the output. If arr has complex elements, the returned type is float.
