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 to nearest Fields: AwayFromZero ToEven A round-to-nearest operation takes an original number with an implicit or specified precision; examines the next digit, which is at that precision plus one; and returns the nearest number with the same precision as the original number. For positive nu...
一般的四舍五入操作都是使用内置的round方法 In [14]: round(2.675,2) Out[14]: 2.67 文档中这样解释的 The documentation for the built-inround()function says that it rounds to the nearest value, rounding ties away from zero. Since the decimal fraction 2.675 is exactly halfway between 2.67 and...
1. Divide it by the unit to which it is to be rounded 2. Round it to the nearest whole number, unless it ends in exactly .5 3. If it ends in exactly .5, then round towards the nearestevenwhole number 4. Multiply it by the unit to which it is to be rounded ...
对于那些 LOF 异常得分小于等于 1 的,从数据集里剔除,剩下的在下一轮寻找更合适的 nearest-neighbor,并更新 LOF 值。 Python 实现 LOF 有两个库可以计算LOF,分别是PyOD和Sklearn,下面分别介绍。 使用pyod自带的方法生成200个训练样本和100个测试样本的数据集。正态样本由多元高斯分布生成,异常样本是使用均匀分布...
