python标准库的解释及翻译round(number[, ndigits])Return the floating point value number rounded to ndigits digits after the decimal point. If ndigits is omitted, it returns the nearest integer to its input. Delegates to number.__round__(ndigits).For the built-in types...
To get the round value of any float, use built-in function 'round (float, digits after decimal)' . Example: round (4.54321268, 3) >> 4.543 28th Nov 2021, 10:01 PM Prithviraj Kundu + 5 I don't get it why are we use round() function on what situations?
TypeFloat 9 人赞同了该文章 在此之前我从来没有思考过round()的问题,只是简单的认为同数学中的四舍五入并无区别,上课老师谈到之后才明白round()函数并不是严格的四舍五入,而采用四舍六入五看前的准则。这个准则在对一位小数化整数时没有出现任何问题,但是我在尝试使用round()函数将7.55和8.55保留为一位小数...
关于python3round与float的四省五入精度的问题 解决方式: print(Decimal(i["assert_value2"]).quantize(Decimal('0.00'))) 以上解决方案,当i["assert_value2"]='54359.905'时,最终打印的结果会时54359.90,与四省五入值不一致: 由于python3对这个的处理是,当.905离.91与.90距离一样时,取偶数端0.90,那如果...

Note the bankers rounding for 0.5 cases. With precision argument, it rounds to specified decimal places. The function returns a float even when rounding to whole numbers with precision specified. Bankers Rounding ExplainedPython uses "round half to even" (bankers rounding) which minimizes bias in ...
