numpy.isreal(x) [source]

Returns a bool array, where True if input element is real.

If element has complex type with zero complex part, the return value for that element is True.

Parameters:

x : array_like

Input array.

Returns:

out : ndarray, bool

Boolean array of same shape as x.

See also

isrealobj: Return True if x is not a complex type.

Examples

>>> np.isreal([1+1j, 1+0j, 4.5, 3, 2, 2j])
array([False,  True,  True,  True,  True, False], dtype=bool)
