Struct ExactPoint2 

pub struct ExactPoint2 {
    pub x_num: [f64; 16],
    pub x_num_len: usize,
    pub y_num: [f64; 16],
    pub y_num_len: usize,
    pub den: [f64; 8],
    pub den_len: usize,
}

An exact point in 2D, constructed as a rational pair: x = x_num / den, y = y_num / den, where den > 0.

The expansions are stack-allocated (zero-heap). The denominator is shared between x and y (this is the natural form for segment intersection).

Fields

x_num: [f64; 16]

Numerator of the x-coordinate (expansion).

x_num_len: usize

y_num: [f64; 16]

Numerator of the y-coordinate (expansion).

y_num_len: usize

den: [f64; 8]

Shared denominator (expansion). Always positive by construction.

den_len: usize
