Python Math Inbuilt Functions
In python a number of mathematical operations can be performed with ease by importing a module named “math” which defines various functions which makes our tasks easier.
ceil():
This function returns the smallest integral value greater than the number. If the number is already an integer, the same number is returned.
floor():
This function returns the greatest integral value smaller than the number. If number is already integer, same number is returned.
Example:1
import math
print("ceil function")
a=2.3
print(math.ceil(a))
a=12.9
print(math.ceil(a))
a=12.23
print(math.ceil(a))
a=62.36
print(math.ceil(a))
Output:
ceil function
3
13
13
63
>>>
Example:2
import math
print("floor function")
a=23.67
print(math.floor(a))
a=23.17
print(math.floor(a))
a=23.77
print(math.floor(a))
a=23.99
print(math.floor(a))
Output:
floor function
23

Method:2
Example:3
#Method:2
from math import ceil
from math import floor
print("ceil function")
a=2.3
print(ceil(a))
a=12.9
print(ceil(a))
print("floor function")
a=23.67
print(floor(a))
a=23.97
print(floor(a))
Output:
ceil function
3
13
floor function
23
23
>>>
Method:3
Example:4
Method:3
from math import ceil as c
from math import floor as f
print("ceil function")
a=2.3
print(c(a))
a=12.9
print(c(a))
print("floor function")
a=23.67
print(f(a))
a=23.97
print(f(a))
Output:
ceil function
3
13
floor function
