Inversing numeric columns +/-

[peegee68]

Hi,

I'm a rookie stuck on this one, and after searching around for a little while thought I'd ask the community for help.

I have created a custom column to work out the difference in days between a Due Date and Today's date.  The calc I've used is:

"Due Date Difference", each Duration.Days(DateTime.Date(DateTimeZone.UtcNow()) - [Due Date]

The results are good, but I want to inverse their +/- so that any due date before the current date is a negative number (overdue) and a future due date is a positive number (coming up due).  Current results show anything due after today's date as negative number, with anything before today's date is positive.

Tried playing around with a few things that resulted in errors.  Saw that multiplying the column by -1 would inverse the numbers but having a problem figuring out whether I can do this in the calc above or do I need another column/formula to do this?

Any assistance appreciated.

Thanks very much for the simple solution.  I did play around with this but must have had the syntax incorrect or something otherwise in the wrong place???

Hey @peegee68,

this formula

Duration.Days(DateTime.Date(DateTimeZone.UtcNow()) - [Due Date]) * -1

is inversing the values:

As you can see the future due date is positive, future, from today's perspective:

From a performance point of view, I recommend calculating the difference and inversing the result in a single formula.

Hopefully, this provides what you are looking for.
