# tf.math.real

Returns the real part of a complex (or real) tensor.

### Used in the notebooks

Used in the tutorials

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

#### For example:

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

If `input` is already real, it is returned unchanged.

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

A `Tensor` of type `float32` or `float64`.
