Floating point system variables on RS6000 [message #714]

Due to some underflow problems, I have noticed that the system variables
!DTOR, !PI, and !RADDEG are floats. Since all arithmetic on the RS6000 is
done in double precision, is there any reason not to store these as double
precision? Aside from the improved precision, it would obviate the need
for the (invisible) conversion from�float to double at the system level.
(I know there is a !DPI double precision system variable.)
