Python | math.ceil() function

In Python, math module contains a number of mathematical operations, which can be performed with ease using the module. math.ceil() function returns the smallest integral value greater than the number. If number is already integer, same number is returned.

Syntax: math.ceil(x)

Parameter:
x: This is a numeric expression.

Returns:  Smallest integer not less than x.
Time Complexity: O(1)
Auxiliary Space: O(1)

Code #1: 

Python3

# Python code to demonstrate the working of ceil()

# importing "math" for mathematical operations
import math

x = 33.7

# returning the ceil of 33.7
print ("The ceil of 33.7 is : ", end ="")
print (math.ceil(x))

Output:

The ceil of 33.7 is : 34

Code #2: 

Python3

# Python code to demonstrate the working of ceil()

# importing "math" for mathematical operations
import math

# prints the ceil using ceil() method
print ("math.ceil(-13.1) : ", math.ceil(-13.1))
print ("math.ceil(101.96) : ", math.ceil(101.96))

Output:

math.ceil(-13.1) :  -13
math.ceil(101.96) :  102
