+
+Do your math ahead of time and embed the result in the binary. Floating-point code is from `compiler_builtins` and `libm` via the [const_soft_float](https://crates.io/crates/const_soft_float) crate. Uses const generics to check shape of inputs, and is `no_std`.
+
+Please file an issue or make a test PR if your use case is not supported.
