+  22.2.4.4 TypedArray ( object )
+
+  This description applies only if the TypedArray function is called with at
+  least one argument and the Type of the first argument is Object and that
+  object does not have either a [[TypedArrayName]] or an [[ArrayBufferData]]
+  internal slot.

+    ...
+    c. Perform ? Set(O, Pk, kValue, true).
+  ...
+
+  9.4.5.9 IntegerIndexedElementSet ( O, index, value )
+
+  ...
+  15. Perform SetValueInBuffer(buffer, indexedPosition, elementType, numValue).
+  ...

+  24.1.1.6 SetValueInBuffer ( arrayBuffer, byteIndex, type, value [ ,
+  isLittleEndian ] )

+  8. If type is "Float32", then
+     a. Set rawBytes to a List containing the 4 bytes that are the result
+        of converting value to IEEE 754-2008 binary32 format using “Round to
+        nearest, ties to even” rounding mode. If isLittleEndian is false, the
+        bytes are arranged in big endian order. Otherwise, the bytes are
+        arranged in little endian order. If value is NaN, rawValue may be set
+        to any implementation chosen IEEE 754-2008 binary64 format Not-a-Number
+        encoding. An implementation must always choose the same encoding for
+        each implementation distinguishable NaN value.
+  9. Else, if type is "Float64", then
+     a. Set rawBytes to a List containing the 8 bytes that are the IEEE
+        754-2008 binary64 format encoding of value. If isLittleEndian is false,
+        the bytes are arranged in big endian order. Otherwise, the bytes are
+        arranged in little endian order. If value is NaN, rawValue may be set
+        to any implementation chosen IEEE 754-2008 binary32 format Not-a-Number
+        encoding. An implementation must always choose the same encoding for
+        each implementation distinguishable NaN value.
