Python Number floor() Method



The floor() method in Python number returns the floor of x where x is the largest integer but not greater than x. It is one of the Mathematical functions available in the Python math Library. The purpose of this function of Python Programming language is to return a value which is lesser than or is equal to a specific expression or value.


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.


  • x − This is a numeric expression.

Return Value

This method returns largest integer not greater than x.


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

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)

When we run above program, it produces 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
