# vvremainder(_:_:_:_:) Calculates the remainder after dividing each element in an array by the corresponding element in a second array of double-precision values. ``` func vvremainder(_: UnsafeMutablePointer, _: UnsafePointer, _: UnsafePointer, _: UnsafePointer) ``` ## Discussion ### Parameters: - parameter 1: The output array, *z*. - parameter 2: The numerators input array, *y*. - parameter 3: The denominators input array, *x*. - parameter 4: The number of elements in the arrays. The following code shows an example of using [`vvremainder(_:_:_:_:)`](/documentation/Accelerate/vvremainder(_:_:_:_:)): ```swift var x: [Double] = [7, 4, 3, 4] var y: [Double] = [2, 5, 10, 30] var z = [Double](repeating: 0, count: x.count) var n = Int32(x.count) vvremainder(&z, &y, &x, &n) print(z) // [2.0, 1.0, 1.0, -2.0] ``` --- Copyright © 2026 Apple Inc.
