math.floor(x) function returns the largest integer less than or equal to x.
Syntax
The syntax to call floor() function is
math.floor(x)
where
Parameter | Required | Description |
---|---|---|
x | Yes | A numeric value. |
If x is infinity, then floor(x) raises OverflowError.
If x is nan, then floor(x) raises ValueError.
Examples
Floor value of floating point number.
Python Program
import math
x = 3.14
result = math.floor(x)
print('floor(x) :', result)
Run Output
floor(x) : 3
Floor value of negative floating point number
Python Program
import math
x = -3.14
result = math.floor(x)
print('floor(x) :', result)
Run Output
floor(x) : -4
Floor value of infinity.
Python Program
import math
x = math.inf
result = math.floor(x)
print('floor(x) :', result)
Run Output
OverflowError: cannot convert float infinity to integer
Floor value of an integer.
Python Program
import math
x = 3
result = math.floor(x)
print('floor(x) :', result)
Run Output
floor(x) : 3
Floor value of nan.
Python Program
import math
x = math.nan
result = math.floor(x)
print('floor(x) :', result)
Run Output
ValueError: cannot convert float NaN to integer
