# tensorplay.functional.is_complex

Source: https://www.tensorplay.cn/docs/generated/tensorplay.functional.is_complex.html

```python
tensorplay.functional.is_complex(input: Tensor) → bool
```

Returns True if the data type of input is a complex data type i.e.,
one of tensorplay.complex64, and tensorplay.complex128.

Parameters:

input ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the input tensor.

Example:

```
>>> tensorplay.is_complex(tensorplay.tensor([1, 2, 3], dtype=tensorplay.complex64))
True
>>> tensorplay.is_complex(tensorplay.tensor([1, 2, 3], dtype=tensorplay.complex128))
True
>>> tensorplay.is_complex(tensorplay.tensor([1, 2, 3], dtype=tensorplay.int32))
False
>>> tensorplay.is_complex(tensorplay.tensor([1.0, 2.0, 3.0], dtype=tensorplay.float16))
False
```
