Question

我想创建这个简单的除法程序。但问题是除数不应该是小数位的答案，我如何把检查。指导将不胜感激。

 Option Explicit

 ' Number Generation '

 liEqua1 = Int(fiMax1 * Rnd) + 1
 liEqua2 = Int(fiMax2 * Rnd) + 1

 liOperand2 = liEqua2

        liOperand2 = liEqua1
    End If
    '**Problem Point**
    liResult = liOperand1 / liOperand2 'liOperand1 / liOperand2 should not be such that answer (liResult) is in decimal places
 End If

Answer 1

如果我理解正确，您只想返回答案的整数部分（商）。为此，您可以使用'\'而不是'/'。

 Dim k As Integer
 k = 23 \ 5 ' sets k to 4.

Answer 2

建议1（避免隐式转换）：

 If CDbl(liResult) = CDbl(liOperand1 / liOperand2) Then
   MsgBox "result is an integer"
 Else
   MsgBox "result is not an integer"
 End If

建议2（根据@Ryan的回答）：

 If (liOperand1 / liOperand2) = (liOperand1 \ liOperand2) Then
   MsgBox "result is an integer"
 Else
   MsgBox "result is not an integer"
 End If

简单的除法答案，没有小数位
