//! A macro library for creating big numbers from literals.
//!
//! See the documentation of each macro for the usage.
//!
//! # Dependency requirement
//!
//! Due the fact that the macros expand to plain tokens, and proc macro crates can't
//! re-export types, it's required to add explicit dependency to the underlying crates
//! when using the macros. Specifically, you need to add the following crates as dependencies
//! to your `Cargo.toml`:
//! * For [ubig!]/[static_ubig!] and [ibig!]/[static_ibig!]: `dashu-int`
//! * For [fbig!]/[static_fbig!] and [dbig!]/[static_dbig!]: `dashu-int`, `dashu-float`
//! * For [rbig!]/[static_rbig!]: `dashu-int`, `dashu-ratio`
//! * For [cbig!]/[static_cbig!]: `dashu-int`, `dashu-float`, `dashu-cmplx`
//!
//! If you are using these macros from the `dashu` crate, then it's not necessary to
//! explicitly adding these dependencies, because the related types are re-exported
//! by the `dashu` crate.
