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...
We can round this numeric value (i.e. the number 77) to the closest 10 by specifying a negative integer to the digits option of round:round(x10, digits = - 1) # Round to nearest 10 # 80Note that this principle can also be applied in order to round to the next 100, 1000, 10000...
def round_to_nearest_cent(value): return int(round(value * 100)) # 示例 print(round_to_nearest_cent(2.555)) print(round_to_nearest_cent(2.545)) # 256 # 254 # 应用二:数据分析和可视化 # 示例1: 清理DataFrame中的数值列 import pandas as pd # 创建一个示例 DataFrame data = { 'A': [...
3.14159 rounded to two decimal places is 3.14. 1. 2.3 使用注意事项 当ndigits为负数时,round()会将数字四舍五入到最接近的10的幂,例如: num=1234rounded_num=round(num,-1)print(f"{num}rounded to the nearest ten is{rounded_num}.") 1. 2. 3. 输出结果: 1234 rounded to the nearest ten i...
There are two overall rounding strategies, round to nearest and directing rounding, and each enumeration field participates in exactly one of these strategies. Round to nearest Fields: AwayFromZero ToEven A round-to-nearest operation takes an original number with an implicit or specified precision; ex...
