Another excel formula situation

Question

I want to be able to display a difference in seconds as (+4.15) or sometimes negatively as (-4.15) and include the parentheses and plus/minus sign.

How can I use a form

Answer 1

Something like this should work:

=TEXT(B1-A1,"+##.##;-##.##")

Though as Jon says - editing the cell format is far more appropriate generally to avoid an issue, select custom and use this:

+##.##;-##.##
