How to get two values after decimal in GSQL?

Hi team I used Double and Float datatype in may GSQL code but the response always comes in Integer, I am using syntax v1 query

FLOAT res = 5/2;
PRINT res; // 2

DOUBLE res = 5/2;
PRINT res; // 2

FLOAT res = (5/2)*1.0;
PRINT res; // 2

Every time I installed the query and then I run for safer side. but response are always in Integer

FLOAT res = 5*1.0/2;
PRINT res; // 2.5
