Last Updated : 08 Mar, 2024

The numpy.ceil() is a mathematical function that returns the ceil of the elements of array. The ceil of the scalar x is the smallest integer i, such that i >= x

Syntax : numpy.ceil(x[, out]) = ufunc ‘ceil’)Parameters : a : [array_like] Input arrayReturn : The ceil of each element with float data-type.

ceil() function

import numpy as np

in_array = [.5, 1.5, 2.5, 3.5, 4.5, 10.1] print ("Input array : \n", in_array)

ceiloff_values = np.ceil(in_array) print ("\nRounded values : \n", ceiloff_values)

in_array = [.53, 1.54, .71] print ("\nInput array : \n", in_array)

ceiloff_values = np.ceil(in_array) print ("\nRounded values : \n", ceiloff_values)

in_array = [.5538, 1.33354, .71445] print ("\nInput array : \n", in_array)

ceiloff_values = np.ceil(in_array) print ("\nRounded values : \n", ceiloff_values)

`

Output :

Input array : [0.5, 1.5, 2.5, 3.5, 4.5, 10.1]

Rounded values : [ 1. 2. 3. 4. 5. 11.]

Input array : [0.53, 1.54, 0.71]

Rounded values : [ 1. 2. 1.]

Input array : [0.5538, 1.33354, 0.71445]

Rounded values : [ 1. 2. 1.]

ceiloff_values = np.ceil(in_array) print ("\nRounded values : \n", ceiloff_values)

in_array = [133.000, 344.54, 437.56, 44.9, 1.2] print ("\nInput array : \n", in_array)

ceiloff_values = np.ceil(in_array) print ("\nRounded values upto 2: \n", ceiloff_values)

`

Output :

Input array : [1.67, 4.5, 7, 9, 12]

Rounded values : [ 2. 5. 7. 9. 12.]

Input array : [133.0, 344.54, 437.56, 44.9, 1.2]

Rounded values upto 2: [ 133. 345. 438. 45. 2.]
