Major Description
Dain first reported this problem on the dev mailing list:
http://www.nabble.com/Float-primary-key--tf3557137.html
>My response:
>Okay, I looked at the spec a bit closer and it looks like we need to allow for floats as primary keys:
>"The primary key (or field or property of a composite primary key) should be one of the following types:
>any Java primitive type; any primitive wrapper type; java.lang.String; java.util.Date;
>java.sql.Date. In general, however, approximate numeric types (e.g., floating point types) should
>never be used in primary keys."
>Although the spec clearly recommends against the use of floating points, floats are a primitive type (or the Float wrapper) and need to be allowed. With no >special "AllowStupidApproximatePrimaryKeys" flag. 
>Am I trying to read too much into the spec or Dain's request? This seems to be something that we need to support.
>>Abe's response:
>>Given the spec section you quoted, you're definitely right. It's something we need to support.
