  ### [QuantizationParameters](https://developers.google.com/edge/api/tflite/swift/Structs/QuantizationParameters)


  ` Parameters that determine the mapping of quantized values to real values. Quantized values can
  be mapped to float values using the following conversion:
  `realValue = scale * (quantizedValue - zeroPoint)`.

  #### Declaration

  Swift

      public struct QuantizationParameters : Equatable, Hashable
