> Issue Type: Bug
> Components: hpl/sql

>
>
> 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 HPL/SQL: cast('10.0' as integer); results in:
> Unhandled exception in HPL/SQL
> java.lang.NumberFormatException: For input string: "10.0"
> at
> java.lang.NumberFormatException.forInputString(NumberFormatException.java:65)
> at java.lang.Long.parseLong(Long.java:589)
> at java.lang.Long.parseLong(Long.java:631)
> at org.apache.hive.hplsql.Var.cast(Var.java:181)
> In Hive:
> hive> select cast('10.0' as integer);
> 10
> Time taken: 4.563 seconds, Fetched: 1 row(s)
> hive> select cast('10.3' as integer);
> 10
