Clash.Num.Overflowing

Description

 
Synopsis

Documentation

data Overflowing a Source #

An overflowing number behaves similarly to a Wrapping number, but also includes an overflow status flag which can be used to more easily check if an overflow has occurred.

Numbers can be converted to be Overflowing using toOverflowing.
