Struct Linear

pub struct Linear {
    pub a: f64,
    pub b: f64,
}

A struct that contains the constants of an equation in the form ax + b. Some useful functions are also implemented.

Fields

a: f64

b: f64

Implementations

impl Linear

pub fn new(a: f64, b: f64) -> Self

Creates a new Linear from the values given.

pub fn new_i(a: i32, b: i32) -> Self

Creates a new Linear from the values given.

pub fn root(&self) -> Result<f64, &str>
