Explain ceil(x) in python.

1.	Explain ceil(x) in python.
Answer» ceil(x) Description : The method ceil( ) returns ceiling value of x-the smallest integer not less than x. 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: # !/usr/bin/py thon 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), This will produce the 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

ceil(x)

Description : The method ceil( ) returns ceiling value of x-the smallest integer not less than x.

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:

# !/usr/bin/py thon

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),

This will produce the 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
