NumericAdditiveArithmetic

public protocol NumericAdditiveArithmetic : AdditiveArithmetic, Comparable

An one‐dimensional value that can be added and subtracted.

Note

Unlike WholeArithmetic, NumericAdditiveArithmetic does not need a defined scale, allowing conformance by measurements that can use multiple units.

Conformance Requirements:

Classification
  • isPositive Default implementation

    Returns true if self is positive.

    Default Implementation

    Returns true if self is positive.

    Declaration

    Swift

    var isPositive: Bool
  • isNegative Default implementation

    Returns true if self is negative.

    Default Implementation

    Returns true if self is negative.

    Declaration

    Swift

    var isNegative: Bool
  • isNonNegative Default implementation

    Returns true if self is positive or zero.

    Default Implementation

    Returns true if self is positive or zero.

    Declaration

    Swift

    var isNonNegative: Bool
