> This bug is part of a series of issues and surprising behavior I encountered writing
a reporting script that would aggregate values and give rows different classifications based
on an the aggregate. Addressing some or all of these issues would make HPL/SQL more accessible
to newcomers.
> In Var.java:
> {code}
>   public int compareTo(Var v) {
>     if (this == v) {
>       return 0;
>     }
>     else if (v == null) {
>       return -1;
>     }
>     else if (type == Type.BIGINT && v.type == Type.BIGINT) {
>       return ((Long)value).compareTo((Long)v.value);
>     }
>     else if (type == Type.STRING && v.type == Type.STRING) {
>       return ((String)value).compareTo((String)v.value);
>     }
>     return -1;
>   }
> {code}
> It's surprising that comparisons with doubles and decimals (for example) don't work as
expected.
