See the guide: Math > Complex Number Functions

Returns the imaginary part of a complex number.

Given a tensor input of complex numbers, this operation returns a tensor of type float32 or float64 that is the imaginary part of each element in input. All elements in input must be complex numbers of the form \(a + bj\), where a is the real part and b is the imaginary part returned by this operation.

For example:

# tensor 'input' is [-2.25 + 4.75j, 3.25 + 5.75j]
tf.imag(input) ==> [4.75, 5.75]

Args:

• input: A Tensor. Must be one of the following types: complex64, complex128.
• name: A name for the operation (optional).

Returns:

A Tensor of type float32 or float64.
