numpy.floor() in Python Last Updated : 08 Apr, 2025 Summarize Comments Improve Suggest changes Share Like Article Like Report The numpy.floor() function returns the largest integer less than or equal to each element in the input array. It effectively rounds numbers down to the nearest whole number. Let's understand with an example: Python import numpy as np a = [0.5, 1.5, 2.5, 3, 4.5, 10.1] res = np.floor(a) print("Floored:", res) OutputFloored: [ 0. 1. 2. 3. 4. 10.] Explanation: np.floor() function reduces every element of the array 'a' to its floor value.Syntaxnumpy.floor(x)Parameters:x: Input array (array-like)Return Type: Array with the floor of each element (as floats)Examples of numpy.floor()Example 1: With Decimal Values Python import numpy as np a = [0.53, 1.54, 0.71] print("Input:", a) res = np.floor(a) print("Floored:", res) OutputInput: [0.53, 1.54, 0.71] Floored: [0. 1. 0.] Example 2: Precise Decimal Inputs Python import numpy as np a = [0.5538, 1.33354, 0.71445] print("Input:", a) res = np.floor(a) print("Floored:", res) OutputInput: [0.5538, 1.33354, 0.71445] Floored: [0. 1. 0.] Example 3: Mixed Whole and Decimal Numbers Python import numpy as np a = [1.67, 4.5, 7, 9, 12] print("Input:", a) res = np.floor(a) print("Floored:", res) OutputInput: [1.67, 4.5, 7, 9, 12] Floored: [ 1. 4. 7. 9. 12.] Comment More infoAdvertise with us Next Article numpy.floor() in Python M mohit gupta_omg :) Follow Improve Article Tags : Python Python-numpy Python numpy-Mathematical Function Practice Tags : python Similar Reads numpy.floor_divide() in Python numpy.floor_divide(arr1, arr2, /, out = None, where = True, casting = 'same_kind', order = 'K', dtype = None) : Array element from first array is divided by the elements from second array(all happens element-wise). Both arr1 and arr2 must have same shape. It is equivalent to the Python // operator a 3 min read Python | Numpy ndarray.__ifloordiv__() With the help of Numpy ndarray.__ifloordiv__(), we can divide a particular value that is provided as a parameter in the ndarray.__ifloordiv__() method. Value will be divided to each and every element in a numpy array and remember it always gives the floor value after division. Syntax: ndarray.__iflo 1 min read numpy.mod() in Python numpy.mod() is another function for doing mathematical operations in numpy.It returns element-wise remainder of division between two array arr1 and arr2 i.e. arr1 % arr2 .It returns 0 when arr2 is 0 and both arr1 and arr2 are (arrays of) integers. Syntax : numpy.mod(arr1, arr2, /, out=None, *, where 2 min read Python | math.floor() function In Python, math module contains a number of mathematical operations, which can be performed with ease using the module. math.floor() function returns the largest integer not greater than x. If number is already integer, same number is returned. Syntax: math.floor(x) Parameter: x: This is a numeric e 1 min read float() in Python Python float() function is used to return a floating-point number from a number or a string representation of a numeric value. Example: Here is a simple example of the Python float() function which takes an integer as the parameter and returns its float value. Python3 # convert integer value to floa 3 min read Like
