Example 1: How round() works in Python? # for integers print(round(10)) # for floating point print(round(10.7)) # even choice print(round(5.5)) Run Code Output 10 11 6 Here, round(10):rounds the integer to10 round(10.7):rounds the float10.7to nearest integer,11. round(5.5):round...
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...
I would not suggest using the round() method to get the nearest integer, it is because the round() method uses banker's rounds, which can give an expected (for normal use) result. For example: round(2.5) # 2 round(2.5, 0) # 2.0 This post has info about that issue. To get the...

上下舍入值:Python的round()函数 示例:将Python数字四舍五入到最接近的完整整数 向下舍入到下一个整数:Python的math.floor()函数 示例:将值四舍五入到下一个完整整数 舍入到下一个整数:Python的math.ceil()函数 示例:将Python值四舍五入为整数
Theround()function returns a floating point number that is a rounded version of the specified number, with the specified number of decimals. The default number of decimals is 0, meaning that the function will return the nearest integer. ...
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。
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...
