> Consider the following Pig script which casts return values of the SQUARE UDF which are
 tuples of doubles to long. The describe output of B shows it is long, however the result
is still double.
> {code}
> register statistics.jar;
> A = load 'myfloatdata.txt' using PigStorage() as (doublecol:double);
> B = foreach A generate (tuple(long))statistics.SQUARE(doublecol) as squares:(loadtimesq);
> describe B;
> explain B;
> dump B;
> {code}
> ===========================================
> Describe output of B:
> B: {squares: (loadtimesq: long)}
> ===========================================================
> Sample output of B:
> ((7885.44))
> ((792098.2200010001))
> ((1497360.9268889998))
> ((50023.7956))
> ((0.972196))
> ((0.30980356))
> ((9.9760144E-7))
> ===========================================================
> Cause: The cast for Tuples has not been implemented in POCast.java
