You should really have a look at the Prelude and the Standard Libraries.

Well, it depends on *how* you want to convert.

truncate :: (RealFrac a, Integral b) => a -> b
round :: (RealFrac a, Integral b) => a -> b
floor :: (RealFrac a, Integral b) => a -> b
ceiling :: (RealFrac a, Integral b) => a -> b
