Trait for real and complex numbers


lib.rs:

Scalar trait for generic algorithm

Examples

Basic arithmetics with real/complex

use cauchy::Scalar;

fn add_int<A: Scalar>(a: A) -> A {
    a + A::from(1).unwrap()  // A::from is inhereted from num_traits::NumCast
}

fn add_float<A: Scalar>(a: A) -> A {
    a + A::from(1.0).unwrap()
}

fn add_real<A: Scalar>(a: A) -> A::Real {
    a.re() + A::real(1.0)
}

fn add_complex<A: Scalar>(a: A) -> A::Complex {
    a.as_c() + A::complex(1.0, 1.0)  // upcast to complex if real
}

Random number generation

use cauchy::Scalar;
use rand::prelude::*;

fn random_algorithm<A: Scalar>() {
    let mut rng = StdRng::from_entropy();
    let a = A::rand(&mut rng);
}
