uint512 •

This project demonstrates uint512 representation and arithmetic for the solidity language (which is limited to 2**256). It comes with an example implementation, as well as tests.

Arithmetic Support

• Addition (512 + 512 → 512)

• Subtraction (512 - 512 → 512),

• Multiplication (256 × 256 → 512), (512 × 256 → 512)

• Division (512 / 256 → 256)

• Square root (256 → 256) and (512 → 256).

NOTE: All functions are gas optimized as far I know. Feel free to contribute if you know more advanced algorithms, spot possibilities for gas improvements or just want to extend the library.

First time with Forge/Foundry?

See the official Foundry installation instructions.

Then, install the foundry toolchain installer (foundryup) with:

curl -L https://foundry.paradigm.xyz | bash

Now that you've installed the foundryup binary, anytime you need to get the latest forge or cast binaries, you can run foundryup.

So, simply execute:

foundryup

🎉 Foundry is installed! 🎉

Writing Tests with Foundry

With Foundry, tests are written in Solidity! 🥳

Create a test file for your contract in the src/tests/ directory.

For example, src/Greeter.sol has its test file defined in ./src/tests/Greeter.t.sol.

To learn more about writing tests in Solidity for Foundry and Dapptools, reference Rari Capital's solmate repository largely created by @transmissions11.

Configure Foundry

Using foundry.toml, Foundry is easily configurable.

For a full list of configuration options, see the Foundry configuration documentation.

Install DappTools

Install DappTools using their installation guide.
