Python – tensorflow.math.round()
• Last Updated : 11 Jun, 2020

TensorFlow is open-source python library designed by Google to develop Machine Learning models and deep learning  neural networks. round() is used to find element-wise nearest integer of x.

Syntax: tf.math.round(x, name)

Parameter:

• x: It’s the input tensor. Allowed dtype for this tensor are bfloat16, half, float32, float64.
• name(optional): It’s defines the name for the operation.

Returns:
It returns a tensor of same dtype as x.

Example 1:

## Python3

 `# Importing the library``import` `tensorflow as tf`` ` `# Initializing the input tensor``a ``=` `tf.constant([.``2``, ``1.6``, ``3.7``, ``1``], dtype ``=` `tf.float64)`` ` `# Printing the input tensor``print``(``'a: '``, a)`` ` `# Calculating result``res ``=` `tf.math.``round``(a)`` ` `# Printing the result``print``(``'Result: '``, res)`

Output:

```a:  tf.Tensor([0.2 1.6 3.7 1. ], shape=(4, ), dtype=float64)
Result:  tf.Tensor([0. 2. 4. 1.], shape=(4, ), dtype=float64)

```

Example 2: It rounds half to even.

## Python3

 `# importing the library``import` `tensorflow as tf`` ` `# Initializing the input tensor``a ``=` `tf.constant([``2.5``, ``5.5``, ``1.5``, ``6.5``], dtype ``=` `tf.float64)`` ` `# Printing the input tensor``print``(``'a: '``, a)`` ` `# Calculating result``res ``=` `tf.math.``round``(a)`` ` `# Printing the result``print``(``'Result: '``, res)`

Output:

```a:  tf.Tensor([2.5 5.5 1.5 6.5], shape=(4, ), dtype=float64)
Result:  tf.Tensor([2. 6. 2. 6.], shape=(4, ), dtype=float64)
```
