Robert C. Helling 9fd531dcc5 Round gas depth properly 
The D in MOD, EAD, END, and EADD stands for "depth" and
as such these should be mm in int rather than double.

The intermediate fn2 and fhe2, however, as intermediate
value should not be rounded to an integer.

The upshot of this is a litle more numerical stability.
It should lead to more stable values in TestProfile
when run on architectures with different floating
point precision.
