Show HN: A tiny public domain math library written in C (+ web demo)

This is a public domain library that has string/float conversions and an implementation of basic math functions. I did an interactive demo where you can test individual functions and custom expressions. It's mainly useful for WebAssembly where having the smallest sizes of the binaries is a win, but you can use it anywhere where you don't have the traditional C library available. It is not perfect, it is a bit less accurate than established libraries but should suffice for most usages. If you have tips for improvements feel free to post a comment.
