Where are signed 8-bit and 16-bit numbers?

[hirrolot]

In the Signed module, I see only the Int32 and Int64 types, but there is no Int8 and Int16. Are they simply not implemented or I search in a wrong place? From README.md, it follows that Int8 and Int16 should be implemented:

The ocaml-integers library provides a number of 8-, 16-, 32- and 64-bit signed and unsigned integer types

They're currently unimplemented. A PR would be welcome.

This would be pretty helpful for making programming languages!

Edit: Seems like there is a PR about it here: #49?

int_repr seems like an alternative package that supports the full complement of integers up to 128 bits. Unfortunately it requires you to depend on Jane Street’s standard library, as mentioned in this thread.

@brendanzab the documentation of int_repr seems to suggest it supports ints up to 64 bit. Could you please link me to the module implementing 128 bit width?
