     18When WCPS 1.5 translates this WCPS query

     26
     27{{{
     28SELECT complex(2, 3) FROM mr AS c

     30
     31when Petascope execute this query, it throws exception
     32
     33
     34{{{

     45However, this Rasql query can be executed normally in Rasql
     46
     47
     48{{{

     57
     58It works if encode complex number inside "encode( )" operator, here is example:
     59
     60
     61{{{
     62http://localhost:8088/rasdaman/ows?service=WCS&version=2.0.1&request=ProcessCoverages&query=

     64over $x x (0:1),$y y (0:1) values
     65condense over $x x (0:1),$y y (0:1)
     66using (0.1, 0.1),"csv")&wcpsVersion=2.0
     67}}}
     68
     69which returns Rasql
     70
     71
     72{{{
     73SELECT encode(
     74MARRAY x in [0:1,209:210] VALUES
