Swift - remquo() Function
The Swift remquo() function returns the floating-point remainder of x/y (rounded to nearest integer). The function additionally also returns the quotient of the division operation. This can be mathematically expressed as below:
remainder = x - quotient * y
Where quotient is the result of x/y rounded towards nearest integer (with halfway cases rounded toward the even number). The returned value by this function is (remainder, quotient).
Note: The remainder function is similar to the remquo function except it only returns remainder of the division operation.
In Foundation framework, it is defined as follows:
public func remquo(_ x: CGFloat, _ y: CGFloat) -> (CGFloat, Int) public func remquo(_ x: Float, _ y: Float) -> (Float, Int) public func remquo(_ x: Double, _ y: Double) -> (Double, Int) public func remquo(_ x: Float80, _ y: Float80) -> (Float80, Int)
||Specify the value of numerator.|
||Specify the value of denominator.|
Returns (remainder, quotient) of x/y division operation. If the remainder is zero, its sign will be same as that of x. If y is zero, the function returns (-nan, 0).
In the example below, remquo() function is used to find out the remainder and quotient of a given division.
import Foundation var x:Double = 25 var y:Double = 4 var rem:Double var quo:Int print("remquo(25.0, 4.0) = \(remquo(25.0, 4.0))") (rem, quo) = remquo(x, y) print("Remainder = \(rem)") print("Quotient = \(quo)")
The output of the above code will be:
remquo(25.0, 4.0) = (1.0, 6) Remainder = 1.0 Quotient = 6
