Task and Solution in Python - Floor, Ceil and Rint (HackerRank)

 

floor
The tool floor returns the floor of the input element-wise.
The floor of  is the largest integer  where .

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  is the smallest integer  where .

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, . Your task is to print the ,  and  of all the elements of .

Note
In order to get the correct output format, add the line  below the numpy import.

Input Format

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

Output Format

On the first line, print the  of A.
On the second line, print the  of A.
On the third line, print the  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

numpy.set_printoptions(legacy='1.13')

val = numpy.array(input().split(), float)

print(numpy.floor(val))

print(numpy.ceil(val))

print(numpy.rint(val))
