我想要一个函数,我可以插入2个整数,然后返回一个整数作为结果
Sub test()
Dim x As Integer
x = getConst 1, 0 ' here is where i get the error message
MsgBox "Vakue" & x
End Sub
Function getConst(ry As Integer, rx As Integer) As Integer
getConst = 3 'actually that one: getConst = 34 * ry * ry - 30 * ry + 8.5 * rx * rx + 7.5 * rx, but that should make any difference
End Function
我习惯于Java编码,它应该有点像这样,但它说“Erwartet:Anweisungsende”所以用英语〜“Expectet end of clause”
答案 0 :(得分:0)
从函数中检索值需要使用括号
x = getConst(1, 0)
但是当你把它们称为一个程序(没有检索返回值)时,你可以忘记这个假体:
getConst 1, 0

您遇到的唯一问题是Sub Test()
中函数调用周围缺少括号...即
x = getConst(1, 0)
在实际函数中,你应该重新考虑使用整数变量乘以小数。
Sub test()
Dim x As Integer
x = getConst(1, 0)
MsgBox "Value " & x
End Sub
Function getConst(ry As Integer, rx As Integer) As Integer
' getConst = 3 'actually that one:
' getConst = 34 * ry * ry - 30 * ry + 8.5 * rx * rx + 7.5 * rx
' but that should make any difference
getConst = 34 * ry ^ 2 - 30 * ry + 8.5 * rx ^ 2 + 7.5 * rx
End Function
