- 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 fromâ•©float to double at the system level.
- (I know there is a !DPI double precision system variable.)
