> Running the query "select round(stTmpRiepCap.imponibile,1), round(stTmpRiepCap.ritImponibile,1) from StTmpRiepCap stTmpRiepCap", it always returns an Integer and it always truncate the decimal part of Double number ("stTmpRiepCap.imponibile" and "stTmpRiepCap.ritImponibile" are "java.lang.Double").
> Example
> REAL VALUE - Imponibile: 1528.57 -- Ritenuta imponibile 266.13
> VALUE RETURNED USING ROUND - Imponibile: 1528 -- Ritenuta imponibile 266
