Question

即使我的所有数据类型都很好，我也遇到过这个错误。

运行时错误6溢出

这是功能：

Function equation(x As Long) As Long

    Dim a As Long, b As Double

    a = Int(((x - 2) Mod 8) / 6) + 2 * Int((x - 2) / 8)
    b = (x + a - 1) / 2

    equation = Abs(4 * b + 5 + 2 * Int(b))

End Function

当x = 572662307溢出时遇到错误。

Answer 1

x = 572662307。是32位有符号整数（约20亿）的最大值的四分之一，因此您的算术运算可能确实会达到这个值。

在VBA中Long是一个32位有符号整数，不像C＃中那样是64位有符号整数。我建议将a和x更改为Double。

您还可以展开您的功能，以便检查调试器中的所有中间步骤：

Function equation(x As Double) As Double

    Dim a As Double, b As Double, c As Double, d As Double, e As Double, f As Double, g As Double

    a = (x - 2) Mod 8
    b = a / 6
    b = Int( b )

    c = (x - 2) / 8
    d = 2 * Int( c )

    e = b + d
    f = (x + a - 1)
    f = f / 2

    g = 4 * b + 5 + 2 * Int( f )
    equation = Abs( g )

End Function
