`numpy.round()`

is a function in the NumPy library in Python that is used to round the elements of an array to the nearest integer.

The syntax for the `numpy.round()`

function is as follows:

```
numpy.round(a, decimals=0, out=None)
```

`a`

is the input array.`decimals`

specifies the number of decimal places to which the elements of the array should be rounded.`out`

is optional and is used to specify the output array.

The function returns an array with the rounded elements of the input array.

Here are a few examples of how to use the `numpy.round()`

function in Python:

main.py

```
import numpy as np
# Round the numbers in the array to the nearest integer
a = np.array([1.5, 2.3, 3.7, 4.1, 5.9])
b = np.round(a)
print(b)
```

output

```
[2. 2. 4. 4. 6.]
```

main.py

```
import numpy as np
a = np.array([1.5, 2.3, 3.7, 4.1, 5.9])
np.round(a, out=a)
print(a)
```

output

```
[2. 2. 4. 4. 6.]
```

main.py

```
import numpy as np
a = np.array([1.532, 2.387, 3.714, 4.112, 5.998])
b = np.round(a, decimals=2)
print(b)
```

output

```
[1.53, 2.39, 3.71, 4.11, 6. ])
```
