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(3.14...
python 2的官网文档:https://docs.python.org/2/library/functions.html?highlight=round#round 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 (so, for example, round(0.5) is 1.0 and round(-0.5)...
所以round(0.5)会近似到1,而round(-0.5)会近似到-1。 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...

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),如果距离两端一样远,则保留到离0远的一边。所以round(0.5...

Rounding up numbers involves adjusting the digits to give an approximate value. This concept is vital in simplifying numbers to make them easier to work with. The common use cases for rounding up numbers include the following: Financial Calculations: Rounding up is often used in financial calculati...
python3.0及以上 方法/步骤 1 round简介round(number[, ndigits])对浮点数进行近似取值，保留几位小数。第一个参数是一个浮点数，第二个参数是保留的小数位数，可选，如果不写的话默认保留到整数 2 round用法举例>>> round(1.34)1>>> round(1.34,1)1.3>>> round(-1.34)-1>>> round(-1.34,...
