ROUND_HALF_UP表示Round to nearest with ties going away from zero的进位方式,即真正的四舍五入。 注意,Decimal是可以接受浮点数为参数的,我们来看一下: num_3=Decimal(11.245).quantize(Decimal('0.00'),rounding=ROUND_HALF_UP)num_4=Decimal('11.245').quantize(Decimal('0.00'),rounding=ROUND_HALF_UP)...
ROUND HALF EVEN也被称为银行家舍入法,这种舍入方法的规则是:如果数字与两边(相同位数)的数字相等,就向偶数方向舍入,如果不相等,就是就近舍入。( Round to nearest with ties going to nearest even integer. ) 银行家舍入法的具体计算规则: •(1)被修约的数字小于5时,该数字舍去; •(2)被修约的数字...
即Round to nearest with ties going to nearest even integer. 也就是只有在整数部分是奇数的时候, 小数部分才逢5进1; 偶数时逢5舍去。 这有利于更好地保证数据的精确性, 并在实验数据处理中广为使用。 >>> round(2.55, 1)#2是偶数,逢5舍去2.5 >>> format(2.55,'.1f')'2.5'>>> round(1.55, 1)...
由于python3 包括python2.7 以后的round策略使用的是decimal.ROUND_HALF_EVEN。即Round to nearest with ties going to nearest even integer. 也就是只有在整数部分是奇数的时候, 小数部分才逢5进1; 偶数时逢5舍去。 这有利于更好地保证数据的精确性, 并在实验数据处理中广为使用。 二、修改decimal上线文,实现...

round(x.value).astype(int) # Round to the nearest integer and convert to int # Create a DataFrame for the solution solution_df = pd.DataFrame(solution, index=supply_nodes, columns=demand_nodes) print("Optimal Value (Total Transportation Cost):", result) print("Solution (Transportation Plan)...
rounded_number = round(float_number) integer_number = int(rounded_number) # Or simply: int(round(float_number)) print(integer_number) Output: 8 You can refer to the below screenshot to see the output. Theround()function rounds to the nearest integer. If the decimal part is exactly 0.5...
To round to one decimal place, replace .2 with .1: Python >>> n = 7.126 >>> f"The value of n is {n:.1f}" 'The value of n is 7.1' When you format a number as fixed point, it’s always displayed with the precise number of decimal places that you specify: Python >>>...
Q4. In Python, the round() function rounds up or down? The round() function can round the values up and down both depending on the situation. For <0.5, it rounds down, and for >0.5, it rounds up. For =0.5, the round() function rounds the number off to the nearest even number....
Mean of 'n' Nearest Past Neighbors: 使用'k'个最近的过去邻居的均值来填充缺失值,并计算填充后数据与原始数据的均方误差(MSE)。 Seasonal Mean: 使用相应季节期间的均值,它计算了对应季节期间的均值,并使用该均值来填充缺失值。然后,计算填充后数据与原始数据的均方误差(MSE),并绘制填充后的数据与原始数据的比较...
