Explain floor(x) in Python with example.

1.	Explain floor(x) in Python with example.
Answer» The method floor() returns floor of x – the largest integer not greater than x. Syntax: Following is the syntax for floor() method import math math.floor(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 largest integer not greater than x. Example: The following example shows the usage of floor() method. # !/usr/bin/python import math # This will import math module print “math.floor(-45.17): “, math.floor(-45.17) print “math.floor(100.12): “, math.floor(100.12) print “math.floor(100.72): “, math.floor(100.72) print “math.floor(119L):”, math.floor(119L) print “math.floor(math.pi):”, math.floor(math.pi) This will produce the following result: math.floor(-45.17) :-46.0 math.floor(100.12):100.0 math.floor(100.72): 100.0 math.floor(119L): 119.0 math.floor(math.pi): 3.0

Answer»

The method floor() returns floor of x – the largest integer not greater than x.

Syntax: Following is the syntax for floor() method

import math

math.floor(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 largest integer not greater than x.

Example: The following example shows the usage of floor() method.

# !/usr/bin/python

import math # This will import math module print “math.floor(-45.17): “,

math.floor(-45.17)

print “math.floor(100.12): “,

math.floor(100.12)

print “math.floor(100.72): “,

math.floor(100.72)

print “math.floor(119L):”,

math.floor(119L)

print “math.floor(math.pi):”, math.floor(math.pi)

This will produce the following result: math.floor(-45.17) :-46.0

math.floor(100.12):100.0

math.floor(100.72): 100.0

math.floor(119L): 119.0

math.floor(math.pi): 3.0
