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...
round(number[,ndigits]) Return the floating point valuenumberrounded tondigitsdigits after the decimal point. Ifndigitsis omitted, it returns the nearest integer to its input. Delegates tonumber.__round__(ndigits). For the built-in types supportinground(), values are rounded to the closest ...
为了实现这一点,我们可以使用Python的math库中的round函数。 importmath# 找到最近的整数nearest_integer=round(random_number) 1. 2. 3. 4. 在上面的示例代码中,我们使用round函数将random_number取到最近的整数,并将其赋值给nearest_integer变量。 步骤3:输出结果 最后,我们需要将结果打印出来。 # 输出结果print...

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
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...
