Python math.floor() method

math.floor() method is a library method of math module, it is used to get the floor value of a given number, it is used to get the floor value of a number, it accepts a number/numeric expression and returns largest integer (integral) value, which is not greater than the number.

Note: It is useful with the float values if the number is an integer value – it returns the same value.

Syntax of math.floor() method:

    math.floor(n)

Parameter(s): n – a number or numeric expression.

Return value: int – it returns an integer value – which is largest integer value of given number but not greater than the n.

Example:

    Input:
    n = 10.23

    # function call
    print(math.floor(n))

    Output:
    10

Python code to find floor value of a given number

# Python code to find floor value of a given number
# importing math
import math

# number
n1 = 10.23
n2 = 10.67
n3 = 10
n4 = -10.23
n5 = 0

# printing floor values
print("floor(n1): ", math.floor(n1))
print("floor(n2): ", math.floor(n2))
print("floor(n3): ", math.floor(n3))
print("floor(n4): ", math.floor(n4))
print("floor(n5): ", math.floor(n5))

Output

floor(n1):  10
floor(n2):  10
floor(n3):  10
floor(n4):  -11
floor(n5):  0
