tf.real(input, name=None)

tf.real(input, name=None)

See the guide: Math > Complex Number Functions

Returns the real 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 real 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 returned by this operation and b is the imaginary part.

For example:

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

If input is already real, it is returned unchanged.

Args:

• input: A Tensor. Must have numeric type.
• name: A name for the operation (optional).

Returns:

A Tensor of type float32 or float64.
