Sharepoint Development Tips 1-Workflow status code

When you want to retrieve the value of your sharepoint inbuilt workflow and use it somewhere else, say Infopath client/browser forms, the result of getting the string value of them are not like what you see in the web page as "in progress","Rejected",etc, it's all integer status code representing different status. So this is what I found out until now.

In Progress: 2
Approved: 16
Rejected: 17
Canceled: 4
