No Float Support

Hi,
I have been evaluating Jackrabbit and noticed that you can't have a float
property. Is this something thats planed in JSR 283?
The way i got around the problem was to create a price node on my product
node with 2 integer properties, pounds and pence. This might make querying
and sorting pretty hard though.

Are there any other ways to store a float value?

Regards

Ben Short

Hi,

For JCR 1.0, use string, or multiply by 100 and use long.

For JCR 2.0, use decimal:
http://www.day.com/specs/jcr/2.0/5_Reading.html#5.10.4.5%20DECIMAL

Using double is not recommended, because of rounding problems:

is a double not ok for you?

see javax.jcr.Node

public Property setProperty(String name, double value) throws
ValueFormatException, VersionException, LockException,
ConstraintViolationException, RepositoryException;
