Release 0.37.9 (2024-07-31)

• Fix inconsistent lambert w function name #65 (Thanks to @JSorngard)
• Write doc string for special/mod.rs (Link for doc: peroxide/special)

Full Changelog: v0.37.8...v0.37.9

Release 0.37.8 (2024-07-30)

• Integrate with lambert_w crate (#63) (Thanks to @JSorngard)

  • Write flexible wrapper for lambert_w

    pub enum LambertWAccuracyMode {
        Simple,   // Faster, 24 bits of accuracy
        Precise,  // Slower, 50 bits of accuracy
    }
    
    pub fn lambert_w0(z: f64, mode: LambertWAccuracyMode) -> f64;
    pub fn lambert_wm1(z: f64, mode: LambertWAccuracyMode) -> f64;

  • Write default Lambert W function for prelude (Precise as default)

    use peroxide::prelude::*;
    
    fn main() {
        lambert_w0(1.0).print(); // Same as fuga::lambert_w0(1.0, LambertWAccuracyMode::Simple)
    }

What's Changed

• Implement the Lambert W function as a wrapper around the lambert_w crate. by @JSorngard in #63

New Contributors

• @JSorngard made their first contribution in #63
