Need to calculate Age in BI Analysis

Summary

What is the formula needed to calculate age within a BI Analysis?

Content

I am trying to complete a report to calculate the age levels of employees.  I pulled in headcount, and Date of Birth 3 times.  In the second Date of Birth column, I changed the expression to reflect the Current Date.  In the third Date of Birth column I tried to create the formula as I would in Excel: INT((Current Date-Date of Birth)/365).  The INT expression doesn't seem to be available as a function in BI Analysis and I get a formula syntax error when I attempt to run it.  Is there another way to write this formula?
