Crate multicalc 

multicalc — single- and multi-variable calculus for no_std Rust: derivatives, integrals, Jacobians and Hessians, vector-field operators, and Taylor approximation.

Operations are generic over the Numeric scalar trait — implemented for f32 and f64, defaulting to f64 — with transcendentals from libm so it works without std. Fallible operations return utils::error_codes::CalcError.
