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
int函数虽然使用ROUND DOWN方式,但是是取整,得到的结果是integer。如果你的需求是要保留小数点后几位,就要使用decimal模块的接口: >>> from decimal import * >>> Decimal('1.2222').quantize(Decimal('.00'), rounding=ROUND_DOWN) Decimal('1.22') >>> Decimal('1.9999').quantize(Decimal('.00'), roundi...

You can use round() to round a number to the nearest integer:Python >>> round(2.3) 2 >>> round(2.7) 3 round() has some unexpected behavior when the number ends in .5:Python >>> round(2.5) 2 >>> round(3.5) 4 2.5 is rounded down to 2, and 3.5 is rounded up to 4. ...
