Dmitriy V. Ryaboy commented on PIG-2952:
----------------------------------------
Agreed with Jon.
If you want a float to come out, you can always cast i or use 23.0.
This behavior is clearly documented:
http://pig.apache.org/docs/r0.10.0/basic.html#arithmetic
> Division of an integer by an integer returns an integer

> Currently,
> {code}
> a = load 'data' as (i:int);
> b = foreach a generate i / 23;
> {code}

> SQL standard says correct behavior in such cases is to return double. MySQL
> does this correctly as well.
