§Allowance
Math representation of the physically needed permissible deviation of measures in rust avoiding floating point inaccuracy. Allows to calc with allowances aka tolerances in a straight-forth way.
Based of type Measure with a accuracy of 1/10th my-meter (= 0.1μ).
§Exaxmple
use allowance::AllowanceValue;
let width1 = AllowanceValue::new(100.0, 0.05, -0.2);
let width2 = AllowanceValue::with_sym(50.0, 0.05);
// Adding two `AllowancesValue`s is strait-forth.
assert_eq!(width1 + width2, AllowanceValue::new(150.0, 0.1, -0.25));
// `!` inverts the direction of tolerance to /subtract/ measures.
assert_eq!(!width1, AllowanceValue::new(-100.0, 0.2, -0.05));
// Adding an inverted `AllowanceValue` wides the tolerance.
assert_eq!(width1 + !width1, AllowanceValue::new(0.0, 0.25, -0.25));Modules§
