math-interpolate is a Rust library that interpolates two points to calculate the third point in between them.
cargo add math-interpolate
use math_interpolate::{interpolate, Point};
let p1 = Point::new(0.0, 0.0); // x, y is 0.0, 0.0
let p2 = Point::new(5.0, 5.0);
let x: f32 = 3.0;
let result = interpolate(p1, p2, x);
println!("The value of y is {}.", result);
