[samigo-team] Regression: number formats of Numeric answers

[David Horwitz]

Hi All,

I seem to have found a serious regression in 2.9:

https://jira.sakaiproject.org/browse/SAM-1793

it seems to have been introduced by SAM-122 (support for scientific 
notation)

In 2.8 and prior either a comma or a full stop could be used to denote a 
decimal separator. The UI still lists the comma as a valid separator 
outside of scientific notation. However gradingService.validate only 
accepts a full stop.

In the case of an upgraded system it means that any students answers 
with a comma will lead to an unhandled exception.

Do we need a complex upgrade to fix all answers (and a fix to the UI 
docs) or is the method buggy?

Regards

David
