How to use the itk/FloatTypes.Float64 function in itk

case IntTypes.Int32:
      componentSize = 4
      break
    case IntTypes.UInt32:
      componentSize = 4
      break
    case IntTypes.Int64:
      componentSize = 8
      break
    case IntTypes.UInt64:
      componentSize = 8
      break
    case FloatTypes.Float32:
      componentSize = 4
      break
    case FloatTypes.Float64:
      componentSize = 8
      break
    default:
      console.error('Unexpected component type: ' + image.imageType.componentType)
  }
  const numberOfBytes = pixelCount * image.imageType.components * componentSize
  const pipelinePath = 'ZstdDecompress'
  const args = ['input.bin', 'output.bin', String(numberOfBytes)]
  const desiredOutputs = [
    { path: 'output.bin', type: IOTypes.Binary }
  ]
  const inputs = [
    { path: 'input.bin', type: IOTypes.Binary, data: byteArray }
  ]
  console.log(`input MB: ${byteArray.length / 1000 / 1000}`)
  console.log(`output MB: ${numberOfBytes / 1000 / 1000 }`)
