class (Fractional a, Poset a) => Roundable a whereSource
Class for types which can be rounded to integers. The rounding functions in the Prelude are inadequate for floating point because they shoehorn their results into an integral type.
Minimal complete definition: toIntegral and round.
Methods
toIntegral :: Integral b => a -> Maybe bSource
Discards the fractional component from a value. Results in Nothing
if the result cannot be represented as an integer, such as if the input
is infinite or NaN.
class Fractional a => Floating a whereSource
Class for floating point types (real or complex-valued).
Minimal complete definition: everything.
