Truncate in Python

There are many built-in modules in python. Out of these module there is one interesting module known as math module which have several functions in it like, ceil, floor, truncate, factorial, fabs, etc.

Out of these functions there is an interesting function called truncate which behaves as a ceiling function for negative number and floor function for positive number.

Time Complexity: O(1)

Auxiliary Space: O(1)

Python3

# Python program to show output of floor(), ceil()
# truncate() for a positive number.
import math
print (math.floor(3.5)) # floor
print (math.trunc(3.5)) # work as floor
print (math.ceil(3.5))  # ceil

Output:

3.0
3
4.0

In case of negative number

Python3

# Python program to show output of floor(), ceil()
# truncate() for a negative number.
import math
print (math.floor(-3.5)) # floor 
print (math.trunc(-3.5)) # work as ceil
print (math.ceil(-3.5))  # ceil

Output:

-4.0
-3
-3.0

This is because the ceiling function is used to round up, i.e., towards positive infinity and floor function is used to round down, i.e., towards negative infinity.

But the truncate function is used to round up or down towards zero.

numpy.trunc() in Python

The numpy.trunc() is a mathematical function that returns the truncated value of the elements of array. The trunc of the scalar x is the nearest integer i which, closer to zero than x. This simply means that, the fractional part of the signed number x is discarded by this function. Syntax : numpy.tr

struct.pack() in Python

The struct.pack() function in Python converts values like integers and floats into a bytes object based on a specified format. This is useful for storing or transmitting data in binary format. Example: [GFGTABS] Python import struct # Pack an integer (10) as an unsigned short (2 bytes, big-endian) s

f-strings in Python

Python offers a powerful feature called f-strings (formatted string literals) to simplify string formatting and interpolation. f-strings is introduced in Python 3.6 it provides a concise and intuitive way to embed expressions and variables directly into strings.

struct module in Python

This module performs conversions between Python values and C structs represented as Python bytes objects. Format strings are the mechanism used to specify the expected layout when packing and unpacking data. Module struct is available in Python 3.x and not on 2.x, thus these codes will run on the Py

Python str() function

The str() function in Python is an in-built function that takes an object as input and returns its string representation. It can be used to convert various data types into strings, which can then be used for printing, concatenation, and formatting. Letâ€™s take a simple example to converting an Intege

A string is a sequence of characters. Python treats anything inside quotes as a string. This includes letters, numbers, and symbols. Python has no character data type so single character is a string of length 1. [GFGTABS] Python s = "GfG" print(s[1]) # access 2nd char s1 = s + s[0] # updat

Python String - printable()

In Python string.printable is a pre-initialized string constant that contains all characters that are considered printable. This includes digits, ASCII letters, punctuation, and whitespace characters. Let's understand with an example: [GFGTABS] Python import string # to show the contents of string.p

Python range() function

The Python range() function returns a sequence of numbers, in a given range. The most common use of it is to iterate sequences on a sequence of numbers using Python loops. Example In the given example, we are printing the number from 0 to 4. [GFGTABS] Python for i in range(5): print(i, end="
