Python Number abs() Method


Contents

Description

The ceil() Python number method is supposed to return the ceiling value of x, where x is the smallest integer but not less than x. The ceil() method in Python is, therefore, one of the Python Math function which is used for returning the lowest integer value which is, further greater than or equal to the specific expression or number. In case the number already stands to be an integer then, in that case, a similar number is returned.

Syntax

Following is the syntax for ceil() method:

import math

math.ceil( x )

Note − This function is not accessible directly, so we need to import math module and then we need to call this function using math static object.

Parameters

  • x − This is a numeric expression.

Return Value

This method returns smallest integer not less than x.

Example

The following example shows the usage of 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)

When we run above program, it produces following result:

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
