Rnd Function
Syntax
Rnd[(seed
)]
seed
Use: Optional
Data Type: Single
Any valid numeric expression.
Return Value
A random number of variant type Single.
Description
Returns a random number.
Rules at a Glance
The behavior of the Rnd function is determined by
seed
, as described in this table:
Number | Rnd generates... |
< 0 | The same number each time, using

> 0 | The next random number in the current sequence |
0 | The most recently generated number |
Not supplied | The next random number in the current sequence |
The Rnd function always returns a value between and 1.
If number isn’t supplied, the Rnd function uses the last number generated as the seed for the next generated number. This means that given an initial seed (
seed
), the same sequence is generated if number isn’t supplied on subsequent calls.
Example
The following example uses the Randomize
statement along with the
Rnd function to fill 100 cells of an Excel
worksheet with random numbers:
Public Sub GenerateRandomNumbers( ) Dim objExcel, objBook, objSheet Dim intRow, intCol ' Start Excel Set objExcel = CreateObject("Excel.Application") ' Get or create active worksheet If objExcel.ActiveSheet Is Nothing Then Set objBook = objExcel.Workbooks.Add End If Set objSheet = objExcel.ActiveWorkbook.ActiveSheet Randomize ' make Excel visible objExcel.Visible = True ' Set the color of the input text to blue objSheet.Cells.Font.ColorIndex = 5 ' Loop through first 10 rows & columns, ' filling them with random numbers For intRow = 1 To 10 For intCol ...
