You should be able to use sin (toRealFloat a). But I imagine that could
introduce some error into your calculations. You will have to make sure
you put enough type signatures to infer Double.

Hi, I am writing a program to do some astronomical calculation, and I am using the Data.Scientific library to represent my floating point numbers. Would anyone know how to use trigonometric functions with the Scientific type?
I see: a :: Scientific a = scientific 500036 (-5)
sin :: Floating a => a -> a
-- this won't work wrongType = sin a
Any ideas?
