+description: Consistent canonicalization of NaN values
+info: |
+  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.
+
+  ...
+  9. Repeat, while k < len
+    ...
+    c. Perform ? Set(O, Pk, kValue, true).
+  ...
+
+  IntegerIndexedElementSet ( O, index, value )
+
+  Assert: O is an Integer-Indexed exotic object.
+  If O.[[ContentType]] is BigInt, let numValue be ? ToBigInt(value).
+  Otherwise, let numValue be ? ToNumber(value).
+  Let buffer be O.[[ViewedArrayBuffer]].
+  If IsDetachedBuffer(buffer) is false and ! IsValidIntegerIndex(O, index) is true, then
+    Let offset be O.[[ByteOffset]].
+    Let arrayTypeName be the String value of O.[[TypedArrayName]].
+    Let elementSize be the Element Size value specified in Table 62 for arrayTypeName.
+    Let indexedPosition be (ℝ(index) × elementSize) + offset.
+    Let elementType be the Element Type value in Table 62 for arrayTypeName.
+    Perform SetValueInBuffer(buffer, indexedPosition, elementType, numValue, true, Unordered).
+  Return NormalCompletion(undefined).
+
+  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.
