To round to nearest integer towards zero, use the numpy.fix() method in Python Numpy. It rounds an array of floats element-wise to nearest integer towards zero. The rounded values are returned as floats. The 1st parameter, x is an array of floats to be rounded. The 2nd parameter, out is a location into which the result is stored. If provided, it must have a shape that the input broadcasts to. If not provided or None, a freshly-allocated array is returned.

The method returns a float array with the same dimensions as the input. If second argument is not supplied then a float array is returned with the rounded values. If a second argument is supplied the result is stored there. The return value out is then a reference to that array.

## Steps

At first, import the required library −

import numpy as np

Create an array with float type using the array() method −

arr = np.array([120.6, -120.6, 200.7, -320.1, 320.1, 500.6])

Displaying our array −

print("Array...",arr)

Get the datatype −

print("Array datatype...",arr.dtype)


Get the dimensions of the Array −

print("Array Dimensions...",arr.ndim)

Get the number of elements of the Array −

print("Number of elements in the Array...",arr.size)

To round to nearest integer towards zero, use the numpy.fix() method in Python Numpy. It rounds an array of floats element-wise to nearest integer towards zero. The rounded values are returned as floats −

print("Result (rounded)...",np.fix(arr))

## Example

import numpy as np

# Create an array with float type using the array() method
arr = np.array([120.6, -120.6, 200.7, -320.1, 320.1, 500.6])

# Display the array
print("Array...", arr)

# Get the type of the array
print("Our Array type...", arr.dtype)

# Get the dimensions of the Array
print("Our Array Dimension...",arr.ndim)

# Get the shape of the Array
print("Our Array Shape...",arr.shape)

# To round to nearest integer towards zero, use the numpy.fix() method in Python Numpy
# It rounds an array of floats element-wise to nearest integer towards zero. The rounded values are returned as floats.
print("Result (rounded)...",np.fix(arr))

## Output

Array...
[ 120.6 -120.6 200.7 -320.1 320.1 500.6]

Our Array type...
float64

Our Array Dimension...
1

Our Array Shape...
(6,)

Result (rounded)...
[ 120. -120. 200. -320. 320. 500.]
