VBA 函数语法

Question

我正在用以下等式编写函数：

1. P = 10 ^ (A - B9 / ( T + C ))
2. Z = C * Exp ( -k * t)

我使用以下语法：

答案 1：

Function P(a As Integer, b As Integer, c As Integer, t As Integer) As Integer
    P = (10 ^ a) / 10 ^ (b / (t + c))
End Function

答案 2：

Function Z(c As Integer, k As Integer, t As Integer) As Integer
    Z = c / Exp(-k * t)
End Function

答案并不准确。

请让我知道我的不足之处。

Answer 1

方程式与原始方程式不同，您还应该发布某些数字的预期结果，试试这个：

Function P(a As Integer, b As Integer, c As Integer, t As Integer) As Integer
    P = 10 ^ (a - b / (t + c))
End Function

Function Z(c As Integer, k As Integer, t As Integer) As Integer
    Z = c * Exp(-k * t)
End Function

此外，您必须考虑保存Integer的最大值： 32767因此当该变量超过该值时程序将溢出，您可以here阅读有关数据限制的更多信息
