Random Number With Normal Distribution

in VBA the RND function generates a random number using uniform distribution (every number is as likely as any other). Is there a function to generate a random number using normal distribution where the numbers closest to the mean are more likely to occure then numbers further away from the mean. I've created the following custom function to generate a random number between two given values using uniform distribution.

Function RandNum(Min As Double, Max As Double) As Double
RandNum = (Max - Min) * Rnd + Min
End Function
