How to use Floor/Ceiling in a ReportModel expression field?

Question

I\'m working in an SSRS 2005 Report Model Project. I want to create an expression field on a ReportModel that does the same as this C# method:

p         


        

Answer 1

If you cannot find an SSRS solution you can of course create a c# assembly and call it from your report!

Answer 2

It is in fact supported. Use the following expression:

=IIF(delta > 0, ceiling(delta), floor(delta))
