The first approach for rounding decimals in Python we'll discuss in this article is using the round() function. It is a built-in Python function that allows you to round numbers to a specified number of decimal places. It takes two arguments - number and ndigits: round(number, ndigits=...
rounderis a lightweight package for rounding numbers in complex Python objects, such as dictionaries, lists, tuples, and sets, and any complex object that combines any number of such objects in any nested structure; you can also use it for instances of classes whose attributes contain numbers....
When summing many rounded values, the primary school "round half up" algorithm produces a significant and noticeable bias towards larger numbers, artificially inflating the sum; "round half to even" corrects this. If "round half up" semantics arereallynecessary, it can be implemented relatively ea...

The actual values in your cells contain more than 2 decimal places. Therefore, a rounding error appears. I recommend rounding the values in each cell to 2 decimal places using the ROUND function: ROUND(A2,2) I hope this will help, otherwise please do not hesitate to contact me anytime. ...

In the case of our sample values of 1.5 and 2.5, Normal rounding rounds 1.5 to 2. Similarly, banker’s rounding rounds 1.5 to 2. Normal rounding rounds 2.5 to 3. On the other hand, banker’s rounding rounds 2.5 to 2. As you can see, normal rounding rounds up all the time, but ...
