Time Entry - hours is defined as int, but Redmine taskes float

Hi, either the documentation on Time Entry is wrong or even implemtation, will check.

http://python-redmine.readthedocs.io/resources/time_entry.html says that hours must be int
Redmine REST API Documentation on Time Entry did not define int http://www.redmine.org/projects/redmine/wiki/Rest_TimeEntries

Redmine itself takes float numbers, as 2.5 or even -2.5
