UDF to represent middle numbers....

Hi all
i''ve got a question
How can I represent number between two numbers. For example. When you enter {=SUM(ROW(1:10))} ROW functions returns an array representing numbers between 1 and 10 ({1,2,3,4,5,6,7,8,910}).

Basically I need represent by the same way numbers beteween two times. For example. In A1 I have 05:13 and in B1 I have 09:35. When I convert A1 value them to the decimal I get 0.216666666666667 and for B1 value I get 0.399305555555556.
So, in short, i need function that would represent "Middle numbers" like {0.216666666666667, 0.216666666666668, 0.216666666666669....0.399305555555556}

I need it in my calculations....

Thanks for all for your help....

Hi DonkeyOte and thank you for quick responce
Actually I would compare them.
I really need this kind of function. I have even wrote one but it's not working

Function Between(TimeStart As Double, TimeEnd As Double) As Variant
    For TimeStart = TimeStart To TimeEnd
        Between = TimeStart + 0.000000000000001
    Next TimeStart
End Function

I thought this macro would create an array by addind 0.000000000000001 to ecah value between Time start and TimeEnd....

Do you really need to go to that level of significance

Yes, I would like so, and just intersted in creating this kind of formula

Yes, I actually understand that it's wron approach.

It's OK If it is not possible.
