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. Signed-off-by: Robert C. Helling <helling@atdotde.de>
