Floating-Point Operators for Double
Topics
Arithmetic
static func + (Double, Double) -> Double
Adds two values and produces their sum, rounded to a representable value.
static func - (Double, Double) -> Double
Subtracts one value from another and produces their difference, rounded to a representable value.
static func * (Double, Double) -> Double
Multiplies two values and produces their product, rounding to a representable value.
static func / (Double, Double) -> Double
Returns the quotient of dividing the first value by the second, rounded to a representable value.
Arithmetic with Assignment
static func += (inout Double, Double)
Adds two values and stores the result in the left-hand-side variable, rounded to a representable value.
static func -= (inout Double, Double)
Subtracts the second value from the first and stores the difference in the left-hand-side variable, rounding to a representable value.
static func *= (inout Double, Double)
Multiplies two values and stores the result in the left-hand-side variable, rounding to a representable value.
static func /= (inout Double, Double)
Divides the first value by the second and stores the quotient in the left-hand-side variable, rounding to a representable value.
Comparison
static func == (Double, Double) -> Bool
Returns a Boolean value indicating whether two values are equal.
static func == (Double, Double) -> Bool
Returns a Boolean value indicating whether two values are equal.
static func != (Double, Double) -> Bool
Returns a Boolean value indicating whether two values are not equal.
static func < (Double, Double) -> Bool
Returns a Boolean value indicating whether the value of the first argument is less than that of the second argument.
static func < (Double, Double) -> Bool
Returns a Boolean value indicating whether the value of the first argument is less than that of the second argument.
static func <= (Double, Double) -> Bool
Returns a Boolean value indicating whether the value of the first argument is less than or equal to that of the second argument.
static func <= (Double, Double) -> Bool
Returns a Boolean value indicating whether the value of the first argument is less than or equal to that of the second argument.
static func > (Double, Double) -> Bool
Returns a Boolean value indicating whether the value of the first argument is greater than that of the second argument.
static func > (Double, Double) -> Bool
Returns a Boolean value indicating whether the value of the first argument is greater than that of the second argument.
static func >= (Double, Double) -> Bool
Returns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument.
static func >= (Double, Double) -> Bool
Returns a Boolean value indicating whether the value of the first argument is greater than or equal to that of the second argument.
Negation
static func - (Double) -> Double
Calculates the additive inverse of a value.
static func - (Double) -> Double
Returns the additive inverse of the specified value.
static func + (Double) -> Double
Returns the given number unchanged.
Range Expressions
static func ..< (Double) -> PartialRangeUpTo<Double>
Returns a partial range up to, but not including, its upper bound.
static func ... (Double) -> PartialRangeThrough<Double>
Returns a partial range up to, and including, its upper bound.
static func ... (Double) -> PartialRangeFrom<Double>
Returns a partial range extending upward from a lower bound.
