    tf.math.imag(
        input, name=None
    )

Given a tensor `input`, this operation returns a tensor of type `float` that
is the imaginary part of each element in `input` considered as a complex
number. If `input` is real, a tensor of all zeros is returned.

#### For example:

    x = tf.constant([-2.25 + 4.75j, 3.25 + 5.75j])
    tf.math.imag(x)  # [4.75, 5.75]
