  • t is the progress of the tween, ranging from 0 to d.
  • b is the starting value of the property.
  • c is the change between the starting and ending value of the property.
  • d is the total duration
use nice_and_easy::*;

fn main() {
    // Can be used with f32...
    let progress: f32 = 0.5;
    let starting_value: f32 = 0.0;
    let target: f32 = 2.0;
    let duration: f32 = 1.0;
    let value: f32 = sine_in_out(progress, starting_value, target, duration);
    assert_eq!(value, 1.0);

    // ...or f64
    let progress: f64 = 0.5;
    let starting_value: f64 = 0.0;
    let target: f64 = 2.0;
    let duration: f64 = 1.0;
    let value: f64 = quad_in_out(progress, starting_value, target, duration);
    assert_eq!(value, 1.0);
