What are the list workflow approval field values in a REST call?

Question

I looked at the REST call for a list and noticed that the value for approval was

<d:approval m:type="Edm.Int32">16</d:approval> 

for 'Approved' and

 <d:approval m:type="Edm.Int32">2</d:approval> 

for 'In Progress'

What are the other values for the approval field?
