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.

This function is equivalent to allclose except that masked values are treated as equal (default) or unequal, depending on the masked_equal argument.

The tolerance values are positive, typically very small numbers.

Syntax : numpy.issubclass_(arg1, arg2) Parameters : arg1 : [class] Input class. True is returned if arg1 is a subclass of arg2. arg2 : [class or tuple of classes] Input class. If a tuple of classes, Tr 1 min read round() function in Python Python round() function is a built-in function available with Python. It will return you a float number that will be rounded to the decimal places which are given as input. If the decimal places to be rounded are not specified, it is considered as 0, and it will round to the nearest integer.

In Python, breaking a function allows us to exit from loops within the function. With the help of the return statement and the break keyword, we can control the flow of the loop.Using return keywordThis statement immediately terminates a function and optionally returns a value.

This function takes a scalar or array-like object and indicates whether values are missing (``NaN`` in numeric arrays, ``None`` or ``NaN`` in object arrays, ``NaT`` in datetimelike).
