What you are experiencing is referred to as 'integer math', where SQL Server will process two integer numbers in a divide option and return a value of an integer, e.g. 9 / 2 = 4 instead of 4.5
integer-math.jpgTo get a return value with decimal places, then you'll have to convert one of the values in the division to contain decimal values.

I don't have a picture handy, but it'll likely be as simple as using a function that converts to a data type that supports decimal values, such as CDbl(), CSng(), etc.

=Sum(Fields!TotalDays.Value, "dsTotalDays") \ CSng(Sum(Fields!DocumentCount.Value, "dsDocumentCont"))

Change the operator (\ for /):
=Sum(Fields!TotalDays.Value, "dsTotalDays") / Sum(Fields!DocumentCount.Value, "dsDocumentCont")
