Math representation of the physically needed permissible deviation of measures in Rust avoiding floating point inaccuracy. Allows to calculate with tolerance ranges in a consistent way.
Based of an own type Myth with a accuracy of 1/10th my-meter (= 0.1μ).
use tolerance::T128;
fn main() {
let width1 = T128::new(100.0, 0.05, -0.2);
let width2 = T128::with_sym(50.0, 0.05);
// Adding two `T128`s is straightforward.
assert_eq!(width1 + width2, T128::new(150.0, 0.1, -0.25));
// `!` inverts the direction of tolerance to /subtract/ measures.
assert_eq!(!width1, T128::new(-100.0, 0.2, -0.05));
// Adding an inverted `T128` wides the tolerance.
assert_eq!(width1 + !width1, T128::new(0.0, 0.25, -0.25));
}A 128bit wide value. Based on a Myth64 (64bit) for the value it could handle sizes up to +/-922_337_203 km
with a deviation of +/-214 m (Myth32).
based on a Myth32 (32bit) for the value it could handle sizes up to +/-214 m
with a deviation of +/-3 mm (Myth16).
