      Description

      rec:=record
      string id;
      real val;
      end;
      ds:=dataset([

      {'a',1}

      ,

      {'b',-2}

      ],rec);

      ds2:=project(ds,transform(recordof(ds),self.val:=left.val/power(left.val,0.5),self:=left));
      output(ds2);

      The val for -2 outputs -nan when used in a dataset.

      Alternately,
      //real val2:=-2/power(-2,0.5);
      //output(val2);
      But when the expression is used as a definition it gives compile time error.
      Consistency is missing and a macro like isNaN is not present to check for nan.
