round to nearest even number

KNN is a basic classification and regression method. The input of the k-nn is the characteristic vector of the instance, which corresponds to the point in the feature space, and the output is the category of the instance, which can take multiple

Python built-in functions (55) -- round, python built-in 55 round English document: round( Number[, Ndigits]) Return the floating point value NumberRounded NdigitsDigits after the decimal point. If NdigitsIs omitted, it

In math. when performing data processing, round often encounters a situation where 81.25 retains a decimal number, and the value is 81.2. It is searched by material and math. the round rounding algorithm adopts the banker's rounding algorithm, which

English documents: round (number[, ndigits]) Return The floating point value number rounded to ndigits digits after the decimal point. If ndigits is omitted, it returns the

The round () method returns the decimal point of a numeric value rounded to n digits. Grammar The following is the syntax for the Round () method: Round (x [, N]) Parameters X-This is a numeric value that represents the value that needs to be

The Python version also affects the results, and python2 the x round to the nearest multiple from 0, such as round (0.5) =1, round (-0.5) =-1; Python3 rounds x to the nearest number of even multiples, such as round (0.5) =0, round (1.5) =2.0, round (

Fix (number) and Int (numbers) are integral parts of the returned digits. When number is positive, the two return the same value. For example: Fix (3.6) =3,int (3.6) = 3. When number is negative, Fix removes the decimal part directly, and INT

Let's take a look at an example: 1: DECLARE @Value float 2: SET @Value = 12.1785 3: SELECT '12.1785' as ValueToRound, ROUND(@Value,3) as RoundedValue 4: SET @Value = 12.1745 5: SELECT '12.1745' as ValueToRound,ROUND(@Value,3) as
