Website for converting floating-point numbers to their binary representation (in hexadecimal) - here's the live version.
The backend now uses Rust - see the floattohexcgi-rust directory. It is compiled to WASM with wasm-pack - see the floattohexcgi-rust/floattohexlib-bindgen directory. (the previous version used Python with a C module - see floattohexmodule.c and floattohex.py)
Here's a writeup of when this was rewritten in Rust and support for 16-bit float types was added.
The frontend is built with React - see the floattohex-react directory.
