floor()

floor() method in Python returns floor of x i.e., the largest integer not greater than x.

Syntax:
import math
math.floor(x)

Parameter: 
x-numeric expression. 

Returns: 
largest integer not greater than x.

Below is the Python implementation of floor() method:

# Python program to demonstrate the use of floor() method
  
# This will import math module
import math   
  
# prints the ceil using floor() method
print "math.floor(-23.11) : ", math.floor(-23.11)
print "math.floor(300.16) : ", math.floor(300.16)
print "math.floor(300.72) : ", math.floor(300.72)

Output:

math.floor(-23.11) :  -24.0
math.floor(300.16) :  300.0
math.floor(300.72) :  300.0

ceil()

The method ceil() in Python returns ceiling value of x i.e., the smallest integer not less than x.

Syntax: 
import math
math.ceil(x)
Parameter:
x:This is a numeric expression.
Returns: 
Smallest integer not less than x.

Below is the Python implementation of ceil() method:

# Python program to demonstrate the use of ceil() method
  
# This will import math module
import math   
  
# prints the ceil using ceil() method
print "math.ceil(-23.11) : ", math.ceil(-23.11)
print "math.ceil(300.16) : ", math.ceil(300.16)
print "math.ceil(300.72) : ", math.ceil(300.72)

Output:

math.ceil(-23.11) :  -23.0
math.ceil(300.16) :  301.0
math.ceil(300.72) :  301.0
