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...
To round to one decimal place, replace .2 with .1: Python >>> n = 7.126 >>> f"The value of n is {n:.1f}" 'The value of n is 7.1' When you format a number as fixed point, it’s always displayed with the precise number of decimal places that you specify: Python >>>...
