Enum arthroprod::types::Sign

pub enum Sign {
    Pos,
    Neg,
}

A Sign can be positive or negative.

Ongoing work is being carried out to determine if this is expressive enough for the algebra or whether we need to individually track the sign of a component's magnitude, its handedness and its Alpha sign.

• magSign

• handSign

• uSign

The current implementation is to track Sign as a property of an Alpha and to move sign changes within magnitude and handedness into this signle representation when they occur.

Methods

impl Sign

fn combine_with(&self, j: &Sign) -> Sign

Combine two signs (positive, negative) and return their product under the standard rules of arithmetic.
