guess there is sth wrong with sin(PI)

[Jengamon]

It's the PI as replacing PI with 0.1 doesn't crash the engine

Yup, with the current features rhai is used, using this code:

use rhai::{Engine, EvalAltResult};

pub fn main() -> Result<(), Box<EvalAltResult>> {
    let engine = Engine::new();
    let result = engine.eval::<f32>("PI")?;
    println!("Answer: {result}");
    Ok(())
}

I get Error: ErrorVariableNotFound("PI", 1:1)

EDIT: To fix it, you have to call it like a function:

use rhai::{Engine, EvalAltResult};

pub fn main() -> Result<(), Box<EvalAltResult>> {
    let engine = Engine::new();
    let result = engine.eval::<f32>("PI()")?;
    println!("Answer: {result}");
    Ok(())
}

and I've verified that this works in glicol today.
