Synopsis

data Zeroing a
fromZeroing :: Zeroing a -> a
toZeroing :: SaturatingNum a => a -> Zeroing a

Documentation

data Zeroing a Source #

A zeroing number type is one where all operations return zero if they go out of bounds for the underlying type.

Numbers can be converted to zero by default using toZeroing.
