例如,可以使用 Round(Double) 方法将值 3.4 舍入到 3.0,使用 Round(Double, Int32) 方法将值 3.579 舍入到 3.58。在中点值中,结果中最小有效位后面的值正好介于两个数字之间。 例如,如果要舍入到两个小数位数,则 3.47500 是中点值;如果要舍入为整数,则 7.500 是中点值。 在这些情况下,如果使用舍入到最接近的策

Round(number, NumDigitsAfterDecimal)这里的number是要进行四舍五入操作的数字，NumDigitsAfterDecimal是要保留的小数位数。第二步：四舍五入到整数 首先，我们将介绍如何使用Round函数将一个数字四舍五入到最接近的整数。以下是一个示例：Sub RoundToInt()Dim num As Double Dim roundedNum As Double num = 3....
