我想知道在VB.NET中检查可分性的最快方法是什么.
我尝试了以下两个功能,但我觉得好像有更有效的技术.
Function isDivisible(x As Integer,d As Integer) As Boolean
Return Math.floor(x / d) = x / d
End Function
我想出的另一个：
Function isDivisible(x As Integer,d As Integer) As Boolean
Dim v = x / d
Dim w As Integer = v
Return v = w
End Function
这是一种更实用的方法吗？
使用Mod：
Function isDivisible(x As Integer,d As Integer) As Boolean
Return (x Mod d) = 0
End Function
