How are 16-bit signed integers representing mag var pseudo-degrees in the file magdec.bgl converted into "real" degrees?

How are 16-bit signed integers representing mag var pseudo-degrees in the file magdec.bgl converted into "real" degrees?

I may have answered my own question. According to the FS2000 scenery SDK pseudo degrees represent the range 0 -360 with different degrees of precision in 8 bit (byte) 16 bit (word) 32 bit (double word) and 48 bit unsigned integers.
