# vS256Divide(_:_:_:_:)

Computes the signed 256-bit division.

## Declaration

```swift
func vS256Divide(_ numerator: UnsafePointer<vS256>, _ divisor: UnsafePointer<vS256>, _ result: UnsafeMutablePointer<vS256>, _ remainder: UnsafeMutablePointer<vS256>?)
```

## Discussion

Discussion important: Apple provides the BLAS and LAPACK libraries under the Accelerate framework to be in line with LAPACK 3.9.1. These new interfaces provide additional functionality, as well as a new ILP64 interface. To use the new interfaces, define ACCELERATE_NEW_LAPACK before including the Accelerate or vecLib headers. For ILP64 interfaces, also define ACCELERATE_LAPACK_ILP64. For Swift projects, specify ACCELERATE_NEW_LAPACK=1 and ACCELERATE_LAPACK_ILP64=1 as preprocessor macros in Xcode build settings under Apple Clang - Preprocessing > Preprocessor Macros.
