# BNNSVectorDescriptor

## Declaration

```swift
struct BNNSVectorDescriptor
```

## Overview

Overview Vector format descriptor (DEPRECATED, Use BNNSNDArrayDescriptor) Represents a vector of dimension size. Each vector element is a scalar value, stored using the type specified in data_type. Component V(i) at index i is stored in data[i], with i=0..size-1. Int types are converted to floating point using float Y = DATA_SCALE * (float)X + DATA_BIAS, and back to integer using Int X = convert_and_saturate(Y / DATA_SCALE - DATA_BIAS)
