Python Numbers

---

Description

The ceil() function returns the ceiling integer of a number.

---

Syntax

The following is the syntax for the ceil() method:

import math

math.ceil( x )

Note:ceil() cannot be accessed directly; you need to import the math module and call the method via a static object.

---

Parameter

x -- a numeric expression.

---

Return Value

The function returns the rounded-up integer of the number.

---

Example

The following shows an example of using the ceil() method:

#!/usr/bin/python
import math   # This will import math module

print "math.ceil(-45.17) : ", math.ceil(-45.17)
print "math.ceil(100.12) : ", math.ceil(100.12)
print "math.ceil(100.72) : ", math.ceil(100.72)
print "math.ceil(119L) : ", math.ceil(119L)
print "math.ceil(math.pi) : ", math.ceil(math.pi)

After running the above example, the output result is:

math.ceil(-45.17) :  -45.0
math.ceil(100.12) :  101.0
math.ceil(100.72) :  101.0
math.ceil(119L) :  119.0
math.ceil(math.pi) : 4.0
