np.around and np.round supports complex numbers, but not np.trunc #17100
Description
Both around and round supports complex input, but not trunc. This looks a bit abnormal.
Reproducing code example:
In [1]: import numpy as np
In [2]: a=np.array([complex(1+1j)]*3)
In [3]: np.around(a)
Out[3]: array([1.+1.j, 1.+1.j, 1.+1.j])
In [4]: np.round(a)
Out[4]: array([1.+1.j, 1.+1.j, 1.+1.j])
In [5]: np.trunc(a)
