End

Implementations

impl Component

pub fn to_float(&self) -> Option<f32>

Attempts to convert the component to a float if it is a number Returns None if component is not a number

Examples

let eq = calculi::Equation::new("a * sqrt(x + 1)");

assert_eq!(eq.solve_with(vec![("a", 2.0), ("x", 8.0)]).to_float().unwrap(), 6.0);
