Python is an interpreted, high-level language that is often used for data science, machine learning and scientific computing. Python has a wide range of built-in math functions that can be used to perform various mathematical operations. One such function is math.rint. The math.rint function is used to round a given number to its nearest integer. In this article, we will discuss the syntax and usage of the math.rint function and its parameters in Python.
What is math.rint(3.6)?
The math.rint(x) function takes a single number as its parameter and rounds it to its nearest integer. For example, math.rint(3.6) will return a result of 4, because 4 is the closest integer to 3.6.
Syntax
The syntax of the math.rint function is as follows:
math.rint(x)
Here, x is the number that needs to be rounded to the nearest integer.
Parameters
x: This is the single number that needs to be rounded to the nearest integer.
Return Value
The math.rint function returns an integer value which is the nearest integer to the given number, x.
Examples
Let’s understand the math.rint function with some examples.
Example 1: Round a Given Number to the Nearest Integer
# Python program to demonstrate math.rint()
# import math module
import math
# use of math.rint()
# a number which needs to be rounded
x = 8.3
# calculus
y = math.rint(x)
# printing the value of y
print("value of y = ", y)
This code will return the following output:
value of y = 8
Example 2: Round a Large Decimal Number to the Nearest Integer
# Python program to demonstrate math.rint()
# import math module
import math
# use of math.rint()
# a number which needs to be rounded
x = 136.85831
# calculus
y = math.rint(x)
# printing the value of y
print("value of y = ", y)
This code will return the following output:
value of y = 137
