Example
use curveipo::{Curve, prelude::*};
// Float curve.
let curve = Curve::new([
// (x, y) curve point
(1.0_f32, -20.0_f32),
(2.0, 2.0),
(10.0, 20.0),
(20.0, -17.0),
]);
// Linear interpolation in float curve with float result.
let x = 3.0;
let y_interpolated = curve.lin_inter(x);
float_eq::assert_float_eq!(y_interpolated, 4.25, abs <= 0.001);
// Integer curve.
let curve = Curve::new([
// (x, y) curve point
(1_i16, -20_i16),
(2, 2),
(10, 20),
(20, -17),
]);
// Linear interpolation in integer curve with rounded integer result.
let x = 3;
let y_interpolated = curve.lin_inter(x);
assert_eq!(y_interpolated, 4);
