• 반올림 (round)

import math

number = 3.14159

rounded_number = round(number)
print(rounded_number) # 출력: 3

 

• 올림 (ceil)

import math

number = 3.14159

rounded_up = math.ceil(number)
print(rounded_up) # 출력: 4

 

• 내림 (floor)

import math

number = 3.14159

rounded_down = math.floor(number)
print(rounded_down) # 출력: 3

 

• 버림

import math

number = 3.14159

rounded_towards_zero = math.copysign(math.floor(abs(number)), number)
print(rounded_towards_zero) # 출력: 3
