combine values

Hi all,Does anybody know how to combine these 2 values and get the difference from them?(A:NAV1 radial,radians) (A:Plane heading degrees gyro,radians) - pi +(A:Plane heading degrees gyro,radians) /-/The first one is from actual radial being tracked by the NAV1.The second one is from the "rose" plate (card) that rotates with the heading on a RMI.I'm trying to find the difference in degrees from the actual radial being tracked and the actual course being flown.Thanks,Benny

Never mind - I just figured it out. I forgot to include the minus at the end after combining them together to find the difference.Benny
