Required Operatorswift 6.0.1Swift

    -(_:_:)

    Subtracts one value from another and produces their difference, rounded to a representable value.

    override static func - (lhs: Self, rhs: Self) -> Self

    Parameters

    lhs

    A numeric value.

    rhs

    The value to subtract from lhs.

    The subtraction operator (-) calculates the difference of its two arguments. For example:

    let x = 7.5
    let y = x - 2.25
    // y == 5.25

    The - operator implements the subtraction operation defined by the IEEE 754 specification.
