trunc(): integer part of a number

import math
print(math.trunc(34.56))   # 34
print(math.trunc(34.21))   # 34
print(math.trunc(34.99))   # 34
print(math.trunc(34))      # 34

import math
print(math.trunc(-34.11))   # -34
print(math.trunc(-34.99))   # -34
print(math.trunc(-34))      # -34

print(math.trunc(123456.789))  # Output: 123456

x = 45.67
print(math.trunc(x))  # Output: 45

Difference between trunc(), floor(), and ceil()

• trunc(): Simply removes the decimal part of the number, returning the integer portion. It does not round the number.

  import math
  print(math.trunc(3.9))  # Output: 3
  print(math.trunc(-3.9))  # Output: -3

• floor(): Rounds the number down to the nearest integer.

  print(math.floor(3.9))  # Output: 3
  print(math.floor(-3.9))  # Output: -4

• ceil(): Rounds the number up to the nearest integer.

  print(math.ceil(3.1))  # Output: 4
  print(math.ceil(-3.1))  # Output: -3
