print(“Rounded down to next integer:\n”, valuesRoundDown) 复制代码 首先,我们导入math模块。这样就可以使用math.ceil()和math.floor()舍入功能。然后,我们创建一个名为的列表values,其中包含多个浮点值。 为了将这些值四舍五入为整数,我们进行了三个列表推导。第一个round()针对每个列表值执行。其他两个在...
输出ROUND_HALF_EVEN,即Round to nearest with ties going to nearest even integer方式进行进位。 我们我们要进行正确的四舍五入,我们将rounding指定为ROUND_HALF_UP即可。我们来看代码: fromdecimalimportDecimalfromdecimalimportROUND_HALF_UP,ROUND_HALF_EVENnum_1=Decimal('0.125').quantize(Decimal('0.00'),rou...
( 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)被修约的数字大于5时,则进位; •(3)被修约的数字等于5时,要看5前面的数字,若是奇数则进位,若是偶数则将5舍掉,即修约后末尾数字都成为偶数;若5的后面还...

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。
