VB Rnd函数是一个伪随机数生成函数，用于生成介于0和1之间的随机数。

它的语法如下：
Rnd([number])
该函数可选的number参数可以是任意正整数类型的表达式，用于指定随机数的种子。

如果省略该参数，则使用系统时间作为种子。

示例：
Sub Example_Rnd()
' 使用系统时间作为种子生成随机数
RandomNumber = Rnd()
' 指定种子数生成随机数
RandomNumber2 = Rnd(13)
' 输出随机数
MsgBox RandomNumber
MsgBox RandomNumber2
End Sub
需要注意的是，Rnd函数只能生成伪随机数，而不是真正的随机数。

因此，如果需要更高质量的随机数，建议使用其他更为严格的随机数生成算法。
