Round(expression[, numdecimalplaces]) 1. 参数 Expression 1. 必选项。数值表达式 被四舍五入。 Numdecimalplaces 1. 可选项。数字表明小数点右边有多少位进行四舍五入。如果省略,则 Round 函数返回整数。 说明 下面的示例利用 Round 函数将数值四舍五入到两位小数: Dim MyVar, pi pi = 3.14159 MyVar = Ro...
原来Python2 的round()是四舍五入,而 Python3 的round()为四舍六入五成双,即高位为单数则进1凑成双数,高位为双数则不进位。 这让我想起了大二时候的大物实验,第一节讲的计数方法,其中印象最深刻的就是“四舍六入五成双”,它的作用是让统计数据更公平,降低舍入的误差。 具体查阅: 浮点算术:争议和限制 ...
