# tensorflow::ops::Angle Class Reference

# tensorflow::ops::Angle

`#include <math_ops.h>`

Returns the argument of a complex number.

## Summary

Given a tensor `input` of complex numbers, this operation returns a tensor of type `float` that is the argument of each element in `input`. [All](https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/ops/all#classtensorflow_1_1ops_1_1_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.

The argument returned by this operation is of the form \\(atan2(b, a)\\).

For example:


```
# tensor 'input' is [-2.25 + 4.75j, 3.25 + 5.75j]
tf.angle(input) ==> [2.0132, 1.056]
```

<br />

(numpy) Equivalent to np.angle.

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object

<br />

Returns:

- `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: The output tensor.
