Data.SatInt

Description

Adapted from SafeInt to perform saturating arithmetic (i.e. returning max or min bounds) instead of throwing on overflow.

This is not quite as fast as using Int or Int64 directly, but we need the safety.

unsafeToSatIntIntSatInt Source #

Wrap an Int as a SatInt. This is unsafe because the Int can be a result of an arbitrary potentially underflowing/overflowing operation.
