The following functions return a decimal datatype if their arguments are decimals: Sum, CumulativeSum, Avg, Median, Count, First, Last, Max, Min, Large, Small, Var, VarP, Mod, Mode, Abs, Case, If.

The following functions return a decimal result instead of a double: CrosstabAvgDec, CrosstabMaxDec, CrosstabMinDec, and CrosstabSumDec.

The Dec function converts a constant string to a decimal.

The Specify Retrieval Arguments dialog box includes the Decimal and Decimal array types.
