  24.2.4.6 DataView.prototype.getFloat64 ( byteOffset [ , littleEndian ] )

  1. Let v be the this value.
  2. If littleEndian is not present, let littleEndian be false.
  3. Return ? GetViewValue(v, byteOffset, littleEndian, "Float64").

  24.2.1.1 GetViewValue ( view, requestIndex, isLittleEndian, type )

  ...
  14. Let bufferIndex be getIndex + viewOffset.
  15. Return GetValueFromBuffer(buffer, bufferIndex, type, isLittleEndian).
  ...

  24.1.1.5 GetValueFromBuffer ( arrayBuffer, byteIndex, type [ , isLittleEndian
  ] )

  ...
  8. If isLittleEndian is false, reverse the order of the elements of rawValue.
