HackerRank Python Solution - Numpy Topic - Floor, Ceil and Rint

Floor:

The tool floor returns the floor of the input element-wise. The floor of x is the largest integer i where i<=x.

import numpy

my_array = numpy.array([1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7, 8.8, 9.9])
print numpy.floor(my_array)         #[ 1.  2.  3.  4.  5.  6.  7.  8.  9.]

Ceil:

The tool ceil returns the ceiling of the input element-wise. The ceiling of x is the smallest integer i where i >= x.

import numpy

my_array = numpy.array([1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7, 8.8, 9.9])
print numpy.ceil(my_array)          #[  2.   3.   4.   5.   6.   7.   8.   9.  10.]

Rint:

The rint tool rounds to the nearest integer of input element-wise.

import numpy

my_array = numpy.array([1.1, 2.2, 3.3, 4.4, 5.5, 6.6, 7.7, 8.8, 9.9])
print numpy.rint(my_array)          #[  1.   2.   3.   4.   6.   7.   8.   9.  10.]

Task:

You are given a 1-D array, A. Your task is to print the floor, ceil, and rint of all the elements of A.

Note:

In order to get the correct output format, add the line numpy.set_printoptions(legacy='1.13') below the numpy import.

Input Format:

A single line of input containing the space-separated elements of array A.

Output Format:

On the first line, print the floor of A.

On the second line, print the ceil of A.

On the third line, print the rint of A.

Sample Input:

1.1 2.2 3.3 4.4 5.5 6.6 7.7 8.8 9.9

Sample Output:

[ 1.  2.  3.  4.  5.  6.  7.  8.  9.]
[  2.   3.   4.   5.   6.   7.   8.   9.  10.]
[  1.   2.   3.   4.   6.   7.   8.   9.  10.]

Solution:

import numpy as np

np.set_printoptions(legacy = '1.13')

ar = np.array(input().strip().split(), float)

print(np.floor(ar), np.ceil(ar), np.rint(ar), sep = "\n")
