Floating-Point Operators for Double

Perform arithmetic and bitwise operations or compare values.

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.
