输出结果: 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.
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 numbers, if the next digit is from 0 throug...
Example 3: Round to Nearest 10 The round function can be used to round to the next 10 (i.e. 10, 20, 30, 40…). Consider the following numeric value: x10<-77# Create number with two digits We can round this numeric value (i.e. the number 77) to the closest 10 by specifying ...
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...
10、结合其他函数使用:round()函数可以与其他数学函数(如sum()、mean()、sqrt()等)结合使用,以在计算过程中进行四舍五入。 round()函数在需要简化浮点数表示、确保数值精度、满足特定格式要求或进行数值舍入的情况下都是非常有用的。 二、round函数使用注意事项 在Python中使用round()函数时,需要牢记以下注意事项...
