Query such as

SELECT FloatNum, 11, MOD(FloatNum, 11) FROM BQT1.SmallA

fails on the PI server with

com.osisoft.rdsa.RdsaException: [PIOLEDBENT] [SQL Analyzer] [Line 1:34] [%] Overload resolution failed for (Single, Single) argument(s).

Similarly for Double arguments. It appears that the modulo operator % is only defined when both arguments are integers (contrary to PI OLEDB Enterprise 2016 User Guide, which states that it is defined for all numeric data types)
