Python math.ceil() method is an efficient way of rounding off a number to its smallest integral value greater than the given number. The exact number is returned if the given number is already an integer.
Syntax
math.ceil(x)
Parameters
x |
Any positive or negative number. |
Returns
The return type of this method is an integer representing the ceiling of x.
Examples
Example Demonstrating Correct Use of math.ceil()
Code Snippet:
import math
x = 0.898762343
value = math.ceil(x)
print(f"The ceiling of {x} is {value}.")
x = -9.5555555
value = math.ceil(x)
print(f"The ceiling of {x} is {value}.")
x = 10
value = math.ceil(x)
print(f"The ceiling of {x} is {value}.")
Output:
The ceiling of 0.898762343 is 1.
The ceiling of -9.5555555 is -9.
The ceiling of 10 is 10.
Note that the parameter should be a valid number. The values may be either positive or negative.
Example Demonstrating an Error While Using math.ceil()
Code Snippet:
import math
# entering a string
x = "Hi"
value = math.ceil(x)
print(f"The ceiling of {x} is {value}.")
# entering a list
x = [1, 2, 3]
value = math.ceil(x)
print(f"The ceiling of {x} is {value}.")
# entering complex numbers
x = 1 + 5j
value = math.ceil(x)
print(f"The ceiling of {x} is {value}.")
# entering an infinite number
x = math.inf
value = math.ceil(x)
print(f"The ceiling of {x} is {value}.")
Output:
Traceback (most recent call last):
File "main.py", line 5, in <module>
value=math.ceil(x)
TypeError: must be a real number, not str

OverflowError: cannot convert float infinity to integer
The above code snippets show all possible syntactic errors when using the math.ceil() method.
