Re: Rounding off double precision

I'm trying some calculations in double precision, and I'd like the
output rounded off so that errors in calculation are not shown. For
instance, the result of COS(90 * 3.141592653589793238d0 / 180.) is
-4.37113886E-06. I'd like it to be zero. Thanks for any help.

For that matter, I also wonder why the result of Cosine is real and
not double precision. Thanks for any clarification.
