// Clippy: reference values and numerical loops in tests / implementations.
#![allow(clippy::excessive_precision)]
#![allow(clippy::unnecessary_cast)]

//! Special mathematical functions for Numra.
//!
//! This crate provides implementations of special functions commonly needed in
//! scientific computing, physics, and engineering.
//!
//! # Function families
//!
//! - **Gamma**: gamma, lgamma, digamma, beta, incomplete gamma/beta
//! - **Error functions**: erf, erfc, erfinv, erfcinv
//! - **Bessel**: J, Y, I, K for real order
//! - **Elliptic integrals**: complete K(m), E(m), incomplete F(phi,m)
//! - **Airy**: Ai(x), Bi(x)
//! - **Hypergeometric**: 1F1, 2F1
//! - **Orthogonal polynomials**: Legendre, Hermite, Laguerre, Chebyshev
//! - **Zeta**: Riemann zeta, Hurwitz zeta
//! - **Misc**: Dawson, Fresnel, Mittag-Leffler
