Module `Checked_oint`Source

checked_oint is an OCaml library for checked integer arithmetic.

This library supports signed and unsigned integers of bitnesses 8, 16, 32, 64, and 128. S is the main signature that contains common operations for all integer types; specific implementations are named U8, U16, and so on.
