Decimals in calculation view

Dears,

We have ECC on HANA.

I've created calculated column "MaterialUnitPrice" in my calculation view for table MBEW.

Code is:

if("LBKUM"!=0,"SALK3"/"LBKUM",0)

MaterialUnitPrice is Double

but result is always rounding to 3 decimals only

but when I tried on SQL console I get correct result

What is the reason for this. Is column engine for calculation view have this limitation?
