Next, we will look at the methods of rounding numbers used in the Python programming language.
This is a built-in function in Python. That is, to use it, you do not need to import any modules. In general, this function entry looks like this:
round ( number, digits )
The first argument is the number to round, and the second is the number of decimal places to keep during the rounding process. If you don't specify the second argument, its value defaults to zero. When using this function, it's important to note that it works differently in different versions of Python.
So, in the second version of Python, rounding is performed thailand telegram data according to the rules of classical arithmetic.
That is, if after the decimal point there are numbers from 1 to 4, then rounding occurs downwards, and if after the decimal point there are numbers from 5 to 9, then rounding occurs upwards. In the third version, rounding occurs according to the so-called "banking" method. This means that rounding occurs to the nearest even number.
For example, let's take the number 4.5 and round it using the bank method. The closest even numbers to it are 4 and 6. This means that the result of rounding will be 4, since the number 4 is closer to the original number than 6. But the number 5.5 will be rounded to 6, since this time the number 6 is closer to the original number than 4.
