Return the Floor of Array Elements in NumPy

To return the floor of the array elements, element-wise, use the numpy.floor() method in Python Numpy. The new location where we will store the result is a new array.

The floor of the scalar x is the largest integer i, such that i <= x. It is often denoted as $\mathrm{\lfloor X \rfloor}$. The function returns the floor of each element in x. This is a scalar if x is a scalar.

The out is a location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.

Steps

At first, import the required library −

import numpy as np

Create an array −

arr = np.array([97.3, 57.4, 100.8, 50.7, -10.5])

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 Dimensions...
", arr.ndim)

Get the number of elements in the Array −

print("
Number of elements...
", arr.size)

Create another array with the same shape to store the result −

arrRes = np.array([5.2, 10.1, 15.7, 20.2, 25.9])

To return the floor of the array elements, element-wise, use the numpy.floor() method in Python Numpy. The new location where we will store the result is arrRes −

print("
Result (floor)...
",np.floor(arr, arrRes))

Check the value of the new array where our result is stored −

print("
Result...
",arrRes)

Example

import numpy as np

# Create an array
arr = np.array([97.3, 57.4, 100.8, 50.7, -10.5])

# 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 Dimensions...
", arr.ndim)

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

# Create another array with the same shape to store the result
arrRes = np.array([5.2, 10.1, 15.7, 20.2, 25.9])

# To return the floor of the array elements, element-wise, use the numpy.floor() method in Python Numpy
# The new location where we will store the result is arrRes
print("
Result (floor)...
",np.floor(arr, arrRes))

# Check the value of the new array where our result is stored
print("
Result...
",arrRes)

Output
