AX 2009 SQLDictionary.FieldType - what are values 45, 49?

Intro Remarks:

I'm not up to speed on X++ yet. I'm used to working directly with the SQL tables to look up data for reporting purposes. I don't do any table updates or changes outside of the application, so don't freak out :)

Question: 
When I look up on MSDN the values for the SqlDictionary.FieldType, it lists value up to "18". 
But when I look at our data, I see records with FieldType = 45 and 49, which are not in the MSDN reference. 

Can anyone tell me what those values represent, or how to look that up in AX 2009?

Thank you, Clark
