Why is euclidian distance being distorted?

[Glitchy-Tozier]

In two places, we calculate the euclidian distance. However, in both implementations, we distort the result by reducing the horizontal distance. Why is that?

impl MatrixPosition {
    /// Euclidean distance to another row/column position on the keyboard
    pub fn distance(&self, other: &MatrixPosition) -> f64 {
        (0.5 * (self.0 as f64 - other.0 as f64).powi(2) + (self.1 as f64 - other.1 as f64).powi(2))
            .sqrt()
    }
}

impl Position {
    /// Euclidean distance to another row/column position on the keyboard
    pub fn distance(&self, other: &Position) -> f64 {
        (0.5 * (self.0 - other.0).powi(2) + (self.1 - other.1).powi(2)).sqrt()
    }
}

That is, indeed, a very good question... Probably a mistake.

Actually … I just checked and it turned out these two methods aren't even used anywhere. At all. They're not even mentioned in any commented-out code.

Should I fix them or remove them?

I guess they can be removed, then. Thanks for finding and removing :)
