This article mainly introduces the floor () method in Python, is the basic knowledge of Python introduction, the need for friends can refer to the
The floor () method returns the largest integer not greater than X (rounding down).
Grammar
The following is the syntax for the floor () method:
?

3import Math
Math.floor (x)
Note: This function is not directly accessible, so we need to import the math module, and then we need to call this function with the static object of math.
Parameters
X--This is a numeric expression.
return value
This method returns the largest integer that is not greater than X.

Import Math # This would 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 the above program, it produces the following results:
