Python:python复制代码rounded_value = round(number, ndigits)其中 number 是要四舍五入的数字,而 ndigits 是要保留的小数位数。例如,round(3.14159, 2) 会返回 3.14。2. Excel:scss复制代码=ROUND(number, num_digits)这里,number 是要四舍五入的数字,而 num_digits 是要保留的小数位数。例如,=ROUND...
round(number[,ndigits]) 1. number:要四舍五入的数字。 ndigits(可选):四舍五入到的小数位数。 2.2 代码示例 以下是一个使用round函数的示例: # 进行四舍五入num=3.14159rounded_num=round(num,2)print(f"{num}rounded to two decimal places is{rounded_num}.") 1. 2. 3. 4. 输出结果: 3.14159...

但是到了python3.5的doc中,文档变成了"values are rounded to the closest multiple of 10 to the power minus ndigits; if two multiples are equally close, rounding is done toward the even choice." 如果距离两边一样远,会保留到偶数的一边。比如round(0.5)和round(-0.5)都会保留到0,而round(1.5)会保留...

了解round 函数的工作原理对于理解其行为和使用方法非常重要。在 Python 中,round 函数的四舍五入规则遵循“银行家舍入法”(Banker’s rounding),也被称为“奇进偶不进”(Round half to even)。 这种舍入规则的特点是,当一个数值精确落在两个相邻的整数中间时,会选择离最近的偶数。例如,round(1.5)的结果是 ...

4 如果我们阅读一下python的文档,里面是这么写的:在python2.7的doc中,round()的最后写着,“Values are rounded to the closest multiple of 10 to the power minus ndigits; if two multiples are equally close, rounding is done away from 0.” 保留值将保留到离上一位更近的一端(四舍六入),...
因此,round(0.5)和round(-0.5)均得出 0 而round(1.5)则为 2。ndigits 可为任意整数值(正数、零或负数)。如果省略了 ndigits 或为 None ,则返回值将为整数。否则返回值与 number 的类型相同。 对于一般的 Python 对象 number, round 将委托给 number.round。
