python round to nearest integer

title: python tutorial: rounding to the nearest integer
introduction:
rounding numbers is a common operation in programming, and python provides a built-in function for this purpose. this tutorial will guide you through the process of rounding numbers to the nearest integer in python, explaining the various options available.
using the round() function:
python's round() function is designed to round a given number to the nearest integer. its syntax is as follows:
example:
in the first example, the positive floating-point number 3.78 is rounded using the round() function. the result is 4, the nearest integer. in the second example, the negative floating-point number -2.56 is rounded to -3.
rounding to a specific number of decimal places:
the round() function can also be used to round a number to a specific number of decimal places by providing a second argument. for instance:
in this example, the floating-point number 5.6789 is rounded to two decimal places, resulting in 5.68.
handling ties:
when rounding to the nearest integer and encountering a tie (e.g., rounding 0.5), python uses the "round half to even" strategy, also known as "bankers' rounding." this means rounding towards the nearest even number.
in this example, the tie number 0.5 is rounded to the nearest even number, resulting in 0.
conclusion:
python's round() function provides a straightforward way to round numbers to the nearest integer. by understanding its basic usage and optional parameters, you can efficiently handle rounding operation
