to get it done, we can use an f-string like this: val = 42.1 print(f'{val:.2f}') # for more details have a look at the python docs result is: 42.10 13th Aug 2024, 12:42 PM Lothar + 4 I would not suggest using the round() method to get the nearest integer, it is ...
4. 使用示例 (Usage Examples) 4.1 四舍五入为整数 (Rounding to the Nearest Integer) print(round(3.6)) # 输出: 4print(round(3.3)) # 输出: 3 在这个示例中,3.6被四舍五入为4,而3.3则被四舍五入为3。 4.2 指定小数位数 (Specifying the Number ofdecimalPlaces) print(round(3.14159, 2)) # 输...
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...
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。
